PROBLEM TO BE SOLVED: To suppress clutter without mounting many auxiliary antennas even when clutter expanded over a wide range of a doppler is present.SOLUTION: Range doppler map RDMis created by performing doppler processing with respect to pulse hit data PHcreated from an input signal S(t) of a main antenna 1, and doppler processing is performed with respect to pieces of pulse hit data PHto PHcreated from input signals S(t) to S(t) of auxiliary antennas 2-1 to 2-N, for creating range doppler maps RDMto RDM, by a range doppler map creation part 4. |
