Abstract:
1. A pulse wave radar device comprising: a transmitting circuit which modulates a first transmitting pulse and a second transmitting pulse which are separated in occurrence from each other by a predetermined time interval and transmits a transmitting pulse wave; a transmitting antenna which transmits the transmitting pulse wave sent from the transmitting circuit; a receiving antenna which receives a receiving pulse wave reflected from a target; a receiving circuit which demodulates the receiving pulse wave from the receiving antenna and outputs a receiving pulse; and a time decision circuit which decides that, if a lapse of time from transmission, by the transmitting circuit, of a transmitting pulse wave corresponding to the first transmitting pulse to outputting of a pulse by the receiving circuit is equal to a lapse of time from transmission, by the transmitting circuit, of a transmitting pulse wave corresponding to the second transmitting pulse to outputting of a pulse by the receiving circuit, the pulses are a receiving pulse reflected from the target.
