<p>PROBLEM TO BE SOLVED: To display an accurate scan-correlative processing result even in an RM/HUP mode, and to display the scan-correletive processing result by a new display mode after switching immediately after the display mode is switched. SOLUTION: Two memory areas 100, 200 are provided on a single radar image processing display memory. A writing address as to the memory area 100 and a writing address as to the memory 200 are generated alternately while synchronized with a writing cycle of the radar image processing display memory. Correlation data written in the memory areas 100, 200 are generated by duplexing correlation data output from a scan-correlative processing circuit on a time base using a delay circuit. Since reading-out for a data in the past is carried out by a TM/NUP mode, the accurate scan-correlative processing result is developed for both of the memory areas 100, 200. The accurate scan correlative processing result is displayed in response to a changing operation of the display mode from the time just after the memory area is switched.</p> |
