<p>PROBLEM TO BE SOLVED: To correctly detect and track a target to meet a high speed of an airframe with its own apparatus loaded and extend a search distance. SOLUTION: A radar transmitter receiver loaded to a moving airframe scans a target with shifting a direction. Received radar video signals obtained during the scanning to the target by the radar transmitter receiver, are inputted for every scanning to a scan integration circuit 211 of a target value operation part 21. Moreover, a correction coefficient calculated by a correction amount calculation circuit 214 is given to an azimuth/distance correction circuit 213 to correct a shift between scannings for every azimuth/distance due to the movement of the airframe. The target value is operated, that is, scan integration is sequentially conducted. A target signal not smaller than a predetermined detection threshold is generated from the received radar video signals.</p> |
