<P>PROBLEM TO BE SOLVED: To solve the problem in which it is difficult to use holographic synthesis at all times in the case where a plurality of targets move at different speeds. <P>SOLUTION: A holographic radar system comprises: a plurality of transmitting antennas (1) which transmit radio waves toward a target; a plurality of receiving antennas (3) which receive reflection waves; a first angle estimation unit (22) which calculates a first angle at which the target is present according to holographic synthesis on the basis of reception waves; a second angle estimation unit (23) which calculates a second angle at which the target is present according to holographic spatial averaging; and a holographic synthesis reliability constant calculation unit (24) which calculates a holographic synthesis reliability constant representing a degree of establishing holographic synthesis. On the basis of at least either the first angle or the second angle and the holographic synthesis reliability constant, the angle of the target is calculated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
