ABSTRACT:
A pulse radar device includes a rectangular signal generating section for generating a rectangular signal that is a reference signal; a transmit timing voltage setting section for setting a voltage value for determining a transmit timing; a transmit pulse generating section for generating a transmit pulse based on the rectangular signal and the voltage value; a receive section for receiving a reflection wave obtained by reflecting the electric wave transmitted by the transmit section by a plurality of objects; a receive saw-tooth wave generating section for generating a saw-tooth wave in synchronism with the transmit pulse; a receive signal sample hold section for sample-holding the receive signal based on the outputs from the saw-tooth wave and the rectangular signal; and a detecting and distance measuring section for detecting the objects and measuring a distance to the objects based on the sample/hold output.
