<P>PROBLEM TO BE SOLVED: To provide a radar signal processing device that has achieved improvement of resolution by simple signal processing without requiring expensive hardware or complex system. <P>SOLUTION: A radar signal processing device 13 is provided with a filtering unit 26 that filters a series of received data consecutive in an azimuth direction. The filtering unit 26 performs the filter while varying the filter coefficient on the basis of the relative sizes of amplitudes of the received data used in arithmetic operation of the filtering. An increase/decrease determining unit 28 determines the trend of variation of the amplitudes of the received data used in arithmetic operation of the filtering by the filtering unit 26. A filter coefficient and tap number determining unit 25 determines the filter coefficient on the basis of the result of the determination, and the filtering unit 26 performs the filtering by using the filter coefficient determined by the filter coefficient and tap number determining unit 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
