Abstract:
A wide-band radar detector with an electronic compass integrated therein, comprising:a radar detecting unit including a first local oscillating unit integrally installed on a side of a horn antenna, a first amplifying unit for amplifying signals from a first mixing unit for mixing oscillation signals having a first local frequency generated from the first local oscillating unit with all the signals received by the horn antenna, a second local oscillating unit that generates oscillation signals, a second amplifying unit for amplifying signals from a second mixing unit for mixing the oscillation signals generated by the second local oscillating unit with the amplified signals from the first amplifying unit, a filtering unit for selectively passing the signals amplified by the second amplifying unit, a demodulating unit for detecting signals that have passed through the filtering unit, an A/D converting unit for converting the detected signals into digital signals, a central processing unit which analyzes and outputs bands of information on the digital signals by measuring and calculating the periods and the widths of the digital signals, and controls the driving of the first and second local oscillating units by generating pulses in order to determine the types of information on the signals over time, a pulse delay unit for delaying or holding the pulses received from the central processing unit, a sweep voltage generating unit for generating a voltage from the pulse delay unit to drive the first local oscillating unit, a laser module integrally formed with the horn antenna for receiving laser signals, a voice producing means for outputting the detected signals to a speaker through a voice amplifying unit, and a visual display means for visually displaying the detected signals; and an electronic compass including a magneto-inductive sensor for sensing earth's magnetic field, and a sensor controlling unit for controlling the magneto-inductive sensor by applying a bias voltage to the magneto-inductive sensor and for transmitting the values sensed by the magneto-inductive sensor to the central processing unit.
