Title: Radar equipment
Inventor: JINRIKI MASANORI
IPC: G01S13/53
Filed: 1982-12-09
Abstract: PURPOSE:To reduce clutter to achieve the enhancement of detection capacity, in a flight body-borne radar for performing electronical beam scanning, by such a simple constitution that the phase shift amount of an antenna element is controlled by operating and correcting a phase corresponding to a scanning mode. CONSTITUTION:An information treatment device 8 calculates third system phase data corresponding to the altitude from a radio wave altimeter 15 to store the same in the phase correcting amount memory circuit 12 of a beam scanning controller 9. When the repeated number of a medium pulse wherein a signal is embedded in side lobe clutter is selected in this state by a controller 1, a earthed switch 14 is changed over during a high pulse repeated frequency mode by the change-over signal (c) from the treatment device 8. By this mechanism, the phase correcting amount of the circuit 12 is added to the phase shift from a phase shift amount operation and controll circuit 10 in an adder 13 while the phase shift amount of the antenna element of a phased array antenna 4 is controlled and only the side lobe below main beam is lowered without deflecting an antenna beam width to a large extent. As a result, clutter due to the sea level and the ground level is reduced and the enhancement of detection capacity can be achieved.

Abstract: PROBLEM TO BE SOLVED: To provide a dielectric multilayered film filter which is further thinner than a conventional filter by constituting the filter of only a multilayered structural body of alternately laminated high refractive index layers and low refractive index layers. SOLUTION: A low refractive index layer 1 is formed on a substrate 4 and then a high refractive index layer 2 is formed thereon. These processes are alternately repeated, and then the substrate 4 is peeled to obtain a dielectric multilayered film filter 3. Therefore, in the obtd. dielectric multilayered film filter 3, the low refractive index layers 1 and high refractive index layers 2 each consisting of a polymer material are alternately laminated. As for the high refractive index layer 2, a material having a large refractive index, especially >2.0 refractive index is preferable. For example, titanium dioxide or tantalum pentoxide is preferable. As for the low refractive index layer 1, various kinds of polymer materials can be used, and polymethylmethacrylate, polycarbonate or the like is preferable.  Thereby, the dielectric multilayered film filter 3 which does not require the substrate 4 for support can be realized so that the filter can be made thin.
