Abstract
The present invention provides a pulse radar apparatus which is capable of detecting properly an object and measuring a distance up to the object in a short distance even if a leakage signal is contained in a received signal. The pulse radar apparatus includes: transmission means for transmitting an electric wave; reception means for receiving the reflected electric wave into which the electric wave transmitted by the transmission means has been reflected by an object to output the received signal thereof; waveform leading part extracting means for extracting a plurality of leading parts of the received signal outputted by the reception means; sampling means for sampling the output of the waveform leading part extracting means at predetermined time intervals; and detection/distance measuring means for judging on the basis of the time interval data outputted by the time interval measuring means whether or not an object is present and when an object is present, calculating the distance up to the object.
