Abstract:
1. A pulse wave radar device comprising: a transmitting signal generation circuit for generating a transmitting signal in which a distance-measuring signal and a user data signal are multiplexed one on the other; an RZ code conversion circuit for generating an RZ propagation signal obtained by RZ-converting the transmitting signal from the transmitting signal generation circuit into a RZ code having a predetermined pulse width; a transmitting circuit for transmitting a transmitting wave obtained by intensity-modulating the RZ propagation signal from the RZ code conversion circuit at a local oscillation frequency; a transmitting antenna for emitting the transmitting wave sent from the transmitting circuit; a receiving antenna for receiving a receiving wave reflected by a target; and a receiving circuit for intensity-demodulating the receiving wave into RZ propagation signal by detecting the receiving wave from the receiving antenna.
