<p>PROBLEM TO BE SOLVED: To provide a pulse radar device capable of precisely detecting an object and measuring the distance, even if a leaked in signal is contained in a receiving signal at a short distance. SOLUTION: This device comprises a transmitting means 101 for transmitting radio waves; a receiving means 103 for receiving the reflected waves of the radio waves transmitted by the transmitting means 101 and reflected by the object; a waveform build-up part extracting means 104 for extracting two or more build-up parts of the received signal outputted by the receiving means 103; a time interval measuring means 105 for measuring the time interval from transmission to reception, on the basis of the extraction result by the extracting means 104; and a detection/range finding means 106 for determining the presence of the object from the time interval data outputted from the measuring means 105 and calculating the distance to the object, when the object is present.</p> |
