<P>PROBLEM TO BE SOLVED: To exactly identify whether a pulse reception wave is a reflected wave of a target or a deceptive interfering wave. <P>SOLUTION: A pulse reception wave is sampled by using a high-speed A/D converter 12 with sampling rate higher than that of a pulse frequency of a pulse transmission wave to detect pulse waveform of the pulse reception wave, reflected wave extractors 14 and 15 specify rise time T1 and droop dr1 of the pulse reception wave from the pulse waveform of the pulse reception wave, and whether the pulse reception wave is a reflected wave of a target or a deceptive interfering wave is identified by comparing the rise time T1 and the droop dr1 of the pulse reception wave with rise time T2 and droop dr2 of the pulse transmission wave. <P>COPYRIGHT: (C)2013,JPO&INPIT |
