Various implementations of a radar system described herein will now be described in more detail with reference to FIGS. 1-7.
FIG. 1 illustrates a block diagram of a radar system 110 in communication with a marine electronics device 600 in accordance with implementations of various techniques described herein. The radar system 110 may include a lighting system 320, a controller 330 (also called a “processor box”) and a radar 350. The marine electronics device 600 may communicate with the radar system 110 over a wireless or wired network connection 165. The controller 330 may include a processor and memory, and may receive commands from the marine electronics device 600 for operating the lighting system 320. In regard to the connection 165, an Ethernet cable may be used between the marine electronics device 600 and the radar system 110, while commands for the lighting system 320 may have one or more dedicated pins on the Ethernet cable. For more information on controlling the lighting system 120 with the marine electronics device 600, see FIGS. 4 and 5 below. For more information regarding the marine electronics device 600, see the section titled MARINE ELECTRONICS DEVICE below.
The radar system 110 may be used in navigation, and positioned or mounted on top of the marine vessel 190. The radar system 110 may detect and track targets using radar signals with the onboard radar 350, while assisting the marine vessel 190 in avoiding obstacles or making a course for a specific target. The radar system 110 may be connected to the marine vessel 190 over connection 155. The connection 155 may include cables for supplying power from the marine vessel 190 to the radar system 110, as well as cables for transmitting data from instruments on the marine vessel 190 to the radar system 110. For more information regarding the radar system 110, see FIG. 3A below.
Keeping with FIG. 1, the lighting system 320 may include one or more light sources disposed in the radar system 110. The lighting system 320 may be configured to direct light beams toward the deck or other specific areas of the marine vessel 190, substantially sideways (i.e., horizontally) away from the marine vessel 190, such as for long-range visibility or navigational lighting, or at predetermined beam angles with respect to the radar system 110 or the marine vessel 190. The lighting system 320 may also be configured to illuminate specific portions of the marine vessel 190, such as a roof or walkway. For more information regarding the lighting system 320, see FIGS. 2A and 3A below.
FIG. 2A illustrates a bottom perspective view of the radar system 110 in accordance with implementations of various techniques described herein. The radar system 110 may include a housing 215 coupled to a pedestal 240. The pedestal 240 may be coupled to an antenna 250. The antenna 250 may be coupled to a radar disposed inside the housing 215. The housing 215 may be one or more contiguous sections (also called “endcaps”) configured to enclose the components of the radar system 110. The housing 215 may include a base 213 configured to be coupled to the marine vessel 190. The pedestal 240 may be configured to support or couple with the antenna 250. The antenna 250 may be part of the radar system 110 or a separate component. Further, the radar system 110 may include one or more light apertures, such as light apertures 217A and 217B, disposed in the housing 215, such that light sources (not shown) may emit light through the light apertures. See FIGS. 2B-2C for side views of the radar system 110 showing light apertures 217A and 217B. In one implementation, light may exit the light apertures 217A-217B at predetermined beam angles with respect to the marine vessel 190, the radar system 110 or the pedestal 240.
Keeping with FIG. 2A, a light pipe 225 (also called a “light tube”) may be disposed inside light aperture 217A. The light pipe 225 may be an optical waveguide configured to transport or distribute light emanating from one or more light sources inside the radar system 110 through the light aperture 217A and outside the radar system 110. The light pipe 225 may be made from a translucent material, such as plastic, or another material configured to produce light beams with specific light characteristics. Specific light characteristics may include attributes such as a particular color of light, beam angles, beam shapes, beam patterns, light intensity (i.e., brightness), luminance or any other specific light characteristics. An example of the light pipe 225 may be seen in FIG. 3B. A sealing gasket (not shown) may be used with sections of the housing 215 and the light pipe 225 to prevent water or debris from entering the radar system 110.
Likewise, the light pipe 225 may be configured to produce light at one or more predetermined beam angles in relation to the radar system 110 or the marine vessel 190. For instance, a wide beam (e.g., a beam angle above 180 degrees) and a narrow beam (e.g., a beam angle less than 45 degrees) may be emanating from the light aperture 217A. Further, the light pipe 225 may be used to produce accent lighting for the marine vessel 190 or a portion of the radar system 110. In one implementation, the light pipe 225 may be configured to direct light beams at a downward angle in respect to a horizontal axis running through the radar system 110 or a horizontal axis substantially parallel to the waterline of the marine vessel 190.
Optical filters, such as Fresnel filters, may also be coupled with the light pipe 225 or a light source disposed inside the radar system 110. An optical filter may absorb, diffuse, or reflect part of a light beam. One example of an optical filter may be a thin-film coating applied to the light pipe 225. As such, the thin-film coating may be used to eliminate or remove one or more specific wavelengths of light passing through the light pipe 225. Other types of filters used in the radar system 110, may include polarizing, haze or warming filters. Optical filters may be used to configure a light aperture to produce light at a predetermined intensity or frequency, such as to produce a glowing effect.
Furthermore, optical filters may be used to remove various portions of light beams emitted by a light aperture. In one implementation, optical filters may be used to produce two or more separate light beams from a light aperture, where the light beams are separated by a predetermined beam angle.
FIG. 2D illustrates an example of the radar system 110 mounted on the marine vessel 190. As shown, light beams emanate from the light apertures 217A (not shown) and 217B. A horizontal light beam 270A and a downward light beam 275A emanate from the light aperture 217A, while a horizontal light beam 270B and a downward light beam 275B emanate from the light aperture 217B. As such, light beams 270A and 275A may be separated by a dark or dim region. This dark or dim region may be generated by configuring a light pipe or an optical filter in a particular aperture to remove a portion of a light beam regarding one or more predetermined beam angles with respect to the particular aperture. While only two separate light beams are shown for the light apertures 217A and 217B, three or more separate light beams may be emanating from a particular aperture. FIG. 2E illustrates a side view of the radar system 110 with light beams 270B and 275B emanating from the light aperture 217B.
FIG. 2F illustrates an example of a dome radar 110A in accordance with implementations of various techniques described herein. The dome radar 110A may include a light aperture 219A that illuminates a ring around the dome radar 110A. The light aperture 219A may be covered to produce an illuminated seal in the dome radar 110A. The dome radar 110A may also include a light aperture 219B that is proximate the base of the dome radar 110A. As such, a downward light beam 275C may emanate from the light aperture 219B. One or more light sources may be positioned in light apertures 219A or 219B.
FIG. 3A illustrates a schematic of the radar system 110 in accordance with implementations of various techniques described herein. The radar system 110 may include a controller 330, a communications interface 333, a radar 350, a power supply 360 and an antenna 370. The communications interface 333 may be used to communicate wirelessly or over a wired connection with the marine electronics device 600 or the marine vessel 190. The controller 330 may include a processor and memory, and may be coupled to the radar 350, the power supply 360 and the lighting system 320. The power supply 360 may be used to provide electric power to various components throughout the radar system 110, such as the light sources 327 and the radar 350.
The radar 350 may include radar components, such as a signal processor, a transmitter for sending radar signals through the antenna 370, a receiver for receiving radar signals from the antenna 370, a voltage oscillator, an amplifier for radar signals received by the antenna 370, one or more filters to block frequency bands of signals received by the antenna 370, or other similar radar components for receiving, transmitting or analyzing radar signals. For more information regarding the operation of radar on a marine vessel or boat, see commonly owned U.S. patent application Ser. No. 13/380,151, filed in the United States on Dec. 22, 2011, now U.S. Pat. No. 9,442,191, with a PCT filing date of Jul. 1, 2010, that was published as U.S. Patent Application Publication Number US 2012/0280854 A1, titled SIGNAL PROCESSING SYSTEM AND METHOD, which is incorporated herein by reference. More information regarding radar operations may be found in commonly owned U.S. patent application Ser. No. 13/474,289, filed on May 17, 2012, now U.S. Pat. No. 9,213,088, that was published as U.S. Patent Application Publication Number US 2012/0293361 A1, titled RADAR CLUTTER SUPPRESSION SYSTEM, which is also incorporated herein by reference.
Furthermore, the radar system 110 may include a lighting system 320 with a circuit board 323, one or more light sources 327 and one or more light pipes 325. In one implementation, the light sources 327 may include light emitting diodes (LEDs), such as surface mounted (SMD) LEDs, that are mounted to the circuit board 323. As such, the circuit board 323 may be a printed circuit board (PCB). An example of LEDs mounted to a PCB is shown in FIG. 3C. The LEDs may be blue, green, red, multi-color, or any other colors or color combinations. While LEDs are shown as light sources in one implementation, other implementations may include fluorescent, halogen, or any other sources of light. FIG. 3D illustrates a portion of the radar system 110 with the light pipe 325A being coupled to light source 327A along and a sealing gasket 326. FIG. 3E illustrates an exploded view of the portion of the radar system 110.
Keeping with FIG. 3A, the lighting system 320 may be configured to emit light at a predetermined luminous intensity. In one example, the light pipes 325 may be configured to smooth the intensity of the light sources 327, e.g., to generate a glowing effect instead of a hot spot. Furthermore, the controller 330 may adjust the intensity emitted by the lighting system 320 through several methods. For instance, the controller 330 may adjust the electrical current going through the circuit board 323 to generate light from the light sources 327 at a low, medium, high or other predetermined intensity levels.
In one implementation, the lighting system 320 may be configured for navigational lighting. For navigational lighting, the lighting system 320 may have one light aperture on the radar system 110 emit red light that signifies the port side of the marine vessel 190 and another light aperture on the radar system 110 emit green light that signifies the starboard side of the marine vessel 190. In another implementation, the lighting system 320 may be configured for anchor lighting, such as to emit white light at substantially 360 degrees around a masthead of the marine vessel 190.
FIG. 4 illustrates a flow diagram of a method 400 for operating the radar system 110 in accordance with implementations of various techniques described herein. In one implementation, method 400 may be performed by the marine electronics device 600. It should be understood that while method 400 indicates a particular order of execution of operations, in some implementations, certain portions of the operations might be executed in a different order. Further, in some implementations, additional operations or steps may be added to the method 400. Likewise, some operations or steps may be omitted. Method 400 may be described with respect to FIGS. 1 and 3A.
At block 410, the marine electronics device 600 may connect to the radar system 110.

Upon initializing a connection, the marine electronics device 600 may receive one or more settings regarding the radar system 110 (i.e., “the radar system settings”). The radar system settings may pertain to the lighting system 320, such as intensity levels for the light sources 327, or operating conditions for the radar 350. The operating conditions for the radar 350 may correspond to conditions for transmitting and/or receiving radar signals from the antenna 350, such as the designated frequency band or the specified receiver gain. Furthermore, the marine electronics device 600 may display the radar system settings. For more information on displaying the radar system settings, see the section titled MARINE ELECTRONICS DEVICE below.
In one implementation, the lighting system 320 may have automatic set times for adjusting settings regarding the radar 350 or the lighting system 320 (e.g., automatically turn ON a light source at a predetermined time, such as 7:00 p.m. or turning OFF a light source at 7:00 a.m.). The automatic set times may be configured on the marine electronics device 600.
At block 420, the marine electronics device 600 may receive an input to adjust or change one or more of the radar system settings. For instance, a user may input a predetermined value into the marine electronics device 600 for a specific radar system setting. For instance, the input may designate the color of light emitted by the light sources 327, the luminous intensity of light emitted by the light sources 327, or any other specific light characteristics regarding the lighting system 320.
At block 430, in response to the input at block 420, the marine electronics device 600 may send lighting control commands to the radar system 110. The lighting control commands may be received by the controller 330 through the communications interface 333 onboard the radar system 110. The lighting control commands may be configured to adjust the lighting system 320 to correspond to the input at block 420. As such, the lighting control commands may be configured to turn ON one or more of the light sources 327, turn OFF one or more the light sources 327, change the intensity level of the lighting system 320, or modify other specific light characteristics regarding the lighting system 320.
At block 440, in response to the input at block 420, the marine electronics device 600 may send radar control commands to the radar system 110. The radar control commands may be configured to adjust the radar 350 to correspond to the input at block 420.

At block 450, the marine electronics device 600 may receive confirmation from the radar system 110 regarding whether the radar system settings were implemented according to the input at block 420. For instance, the radar system 110 may send periodic updates to the marine electronics device 600 regarding the radar system settings, or acknowledgments that the lighting control commands or the radar control commands were received and/or implemented.
FIG. 5 illustrates a flow diagram of a method 500 for modifying various settings of the radar system 110 in accordance with implementations of various techniques described herein. In one implementation, method 500 may be performed by the radar system 110. It should be understood that while method 500 indicates a particular order of execution of operations, in some implementations, certain portions of the operations might be executed in a different order. Further, in some implementations, additional operations or steps may be added to the method 500. Likewise, some operations or steps may be omitted. Method 500 may be described with respect to FIGS. 1 and 3A.
At block 510, the radar system 110 may connect to the marine electronics device 600. The radar system 110 may use a network connection similar to the one described at block 410. During the connection's initialization, the radar system 110 may send the current settings of the lighting system 320 or the radar 350 to the marine electronics device 600.

FIG. 6A illustrates a schematic diagram of the marine electronics device 600 (also called “multi-function display”) in accordance with various implementations described herein. The computing system on the marine electronics device 600 may be described in more detail with reference to FIG. 7. The marine electronics device 600 may be a display device that includes a screen 610 with a graphical user interface 605. The graphical user interface 605 may be configured to send commands to the controller 330 on the radar system 110. These commands may be similar to the ones describes above in connection with the lighting control commands or radar control commands describes in FIGS. 4 and 5. For instance, the graphical user interface 605 may control specific light characteristics from a particular light aperture (e.g., turn ON a light source for light aperture 217A or 217B, set a light source to a maximum intensity level, etc.). The graphical user interface 605 may display data regarding radar system settings such as those described at block 410 of FIG. 4. The graphical user interface 605 may provide icons 635 to control the radar system settings. For instance, the light sources 327 may be turned ON or OFF using icons 635(1) and 635(2), respectively. Light intensity levels for the lighting system 320 may be controlled by the icons for low light intensity 635(3), medium light intensity 635(4) or high light intensity 635(5).
In certain implementations, the screen 610 may be sensitive to touching by a finger. In other implementations, the screen 610 may be sensitive to the body heat from the finger, a stylus, or responsive to a mouse. The marine electronics device 600 may also include a plurality of buttons 620, which may be either physical buttons or virtual buttons, or a combination thereof.
