<P>PROBLEM TO BE SOLVED: To provide a rader device for improving detection performance of a plurality of targets in the space and increasing ranging performance. <P>SOLUTION: A Doppler frequency to be a result of processing of pulse Doppler processing, a beat frequency fb to be a result of RGH processing using one frequency modulation bandwidth, and a distance r<SB POS="POST">pri</SB>inside PRI are used to determine a combination of a plurality of target candidates. A correct combination is selected from among the plurality of combinations. The beat frequency fb and distance r<SB POS="POST">pri</SB>of the respective target candidates related to the combination are used to calculates relative speed v and relative distance R of each of the target candidates. <P>COPYRIGHT: (C)2013,JPO&INPIT |
