<P>PROBLEM TO BE SOLVED: To provide an electronic scanning radar device, a reception wave direction estimation method, a reception wave direction estimation program which detect an arrival direction of a reception wave with a high precision without degradation of detection precision. <P>SOLUTION: A frequency decomposition processing part 22 calculates complex data based on beat signals from a transmission wave and reception waves arriving from targets. A target detection part 31 detects peak values from intensity values of beat frequencies to detect the existence of targets. A target association processing part 32 associates the targets detected in current and past detection cycles. An azimuth detection part 30 makes data generation means generate generation complex data based on the complex data and calculates, per antenna, arrival directions of the reception waves on the basis of normal equations generated using complex data of beat frequencies at which the existence of targets has been detected, and generation complex data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
