<p><P>PROBLEM TO BE SOLVED: To surely output a detection signal indicating that a target has been detected, even when the relative velocity of a radar system and the target becomes large. <P>SOLUTION: The radar system comprises an operation system for operating the range and the Doppler frequency, corresponding to the reflection wave, based on the radiation wave transmitted toward a target direction and the reflection wave of which reflected from the target; a grouping means for grouping the signals outputted from the operation means by each prescribed number of signals; a coherent integration means for coherent integration and outputting the predetermined number of grouped signals; and a detected signal outputting means for outputting the detection signal representing the target is detected, based on the result of the integration. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
