<p><P>PROBLEM TO BE SOLVED: To obtain a radar device with improved detection performance for a target of weak electric power. <P>SOLUTION: This radar device is provided with a receiving means 1 which receives reflected pulses from the target and performs A/D conversion, a pulse compression means 2 which correlates received signals and transmitted signals for every pulse hit, an integration path search means 3 which estimates a range bin where direct waves from the target and indirect waves from the target through a repeater exist and which determines an integration path from a range bin where the indirect waves exist to the range bin where the direct waves exist, a range direction non-coherent integration means 4 which performs non-coherent integration in the range direction along the integration path, a hit direction non-coherent integration means 5 which performs non-coherent integration for the output of the range direction non-coherent integration means 4 acquired for every pulse hit in the hit direction, and a threshold value means 6 which performs threshold processing for the integration result of the hit direction non-coherent integration means 5 and determines as detection of the target for the range bin above a threshold value. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
