<P>PROBLEM TO BE SOLVED: To provide a radar signal processor capable of improving separation precision of speed with the minimum resources. Ž<P>SOLUTION: Rougher Doppler filtering is performed to reception signals by a Doppler filtering section 2, and a peak position of strength distribution is obtained by calculation of the center of gravity using signal strength in each filter bank. Then, high-resolution Doppler filtering is performed only to a filter bank identified from the peak position again in the minimum frequency range. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
