特徴とするレーダ装置。 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. The device includes: an intermediate frequency generation circuit that generates a high frequency signal with the same frequency as the intermediate frequency; a bite mixer circuit that mixes the high frequency signal with a high frequency signal of a local oscillator circuit to obtain a high frequency signal with the same frequency as the transmitted radio wave; A radar device comprising a pulse modulation section that pulse-modulates a high-frequency signal and generates a pseudo reception signal.
