<p>A vehicle has a vehicle speed acquisition section (9) for detecting the speed of movement of the vehicle and outputting a vehicle speed signal. Further, a radar device has a signal creation section (2) for creating a signal to be outputted to space and outputting the created signal, a transmission side amplifier (3) for amplifying the output signal of the signal creation section (2), a transmission antenna (4) for emitting the output signal of the transmission side amplifier (3) to the space, a reception antenna (5) for receiving a reflected wave from an object present in the vicinity and outputting the wave, a reception side amplifier (6) for amplifying the output signal of the reception antenna (5) and outputting the result, a signal processing section (8) for calculating, based on the output signal of the reception side amplifier (6), the distance from the vehicle to the object and/or relative speed, as seen from the vehicle, to the object, and a gain setting section (10) for setting a gain of the transmission side amplifier and/or a gain of the reception side amplifier based on the output signal of the vehicle speed acquisition section (9).</p> |
