ABSTRACT:
Provided is an in-vehicle pulse radar device capable of calculating a distance to a target object based on a delay time between a transmission pulse wave and a received signal. The in-vehicle pulse radar device includes: a reception control unit for controlling passing and blocking of the received signal in synchronization with the transmission pulse wave; a shaping unit for shaping the trailing edge of a pulse wave of the received signal to be delayed; and a sampling unit for sampling the received signal when a predetermined period of time elapses after the reception control unit starts to pass the received signal therethrough.
