るレーダ装置。 A radar that radiates high-frequency pulse power to the outside from the antenna as a transmission radio wave, inputs the reflected power from the target as a reception signal from the antenna, converts it to an intermediate frequency by mixing it with the high-frequency signal of the local oscillator, and extracts radar video. In the device, a frequency-voltage conversion circuit that converts the high-frequency signal of the local oscillator into a voltage proportional to the frequency;
A radar device characterized by comprising a voltage frequency conversion circuit that generates a high frequency signal of the same frequency as the transmitted radio wave from the voltage of the conversion circuit, and a pulse modulation section that pulse modulates this high frequency signal and generates a pseudo reception signal. .
