Title: Wireless detector
Inventor: IZEKI SHUICHI
IPC: G01S7/12
Filed: 2001-08-31
Abstract: PROBLEM TO BE SOLVED: To enable also a sweep unit processing to be performed at the subsequent stage by improving the correspondence relationship between the current data and the past data. SOLUTION: The current data obtained from a buffer memory 13 are sweep data and have correspondence relationship to an antenna relative azimuth. When data after correlation processing created by a write data creating part 14 according to the current data and the past data are written to a scan memory 17 or 18, addressing is performed according to the coordinate system fixed to a loaded ship, thereby retaining the correspondence relationship to the antenna relative azimuth. When the past data are read out of the scan memory 17 or 18 to the write data creating part 14, a read address adjusted according to the turning round amount and the moving amount of the loaded ship from the past to the current time is used.  The current data and the past data in the write data creating part 14 become data related to the same point in the coordinate system fixed to the global surface to improve the correspondence relationship. Since the correlated data corresponds to sweep, CFAR processing in sweep unit can be carried out at a sweep data processing part 15 so as to improve the image quality.
