Claims

[Scope of utility model registration request]

In a radar device that has an oscillator that shares the transmission source of the transmitter and the local oscillation source of the receiver and obtains target distance and speed information, the received signal received by the receiver is used as an intermediate frequency signal, and this intermediate frequency signal is used as an intermediate frequency signal. A gate circuit that allows the frequency signal to pass from zero reception distance, and the output signal from this gate circuit is amplified over time so that the leakage of the transmitted signal is equal to or less than the noise and the short-distance signal is not saturated. A radar device comprising: an STC circuit whose rate changes.
