Title: Radar scan converting device
Inventor: TAKAHASHI HIROSHI
IPC: G01S7/10
Filed: 1989-03-17
Abstract: PURPOSE:To perform writing operation and reading operation fast in parallel by providing >=2 units of video memories which can be stored with quantized video data on a radar image of one raster scan display picture respectively. CONSTITUTION:A video memory switch 8 reads data, which is stored before one turn of an antenna, out of a #1 video memory 4-1 for a raster scan display. Further, a video signal which is inputted currently to an input terminal T1 is inputted to a #2 video memory 4-2 and the data is written in a write address which is converted by a coordinate converter 7 into orthogonal coordinates according to antenna azimuth angle data theta and off-center data XOFF and YOFF inputted from input terminals T2 and T3. When this state continues for one turn of the antenna, the switch 8 switches its internal circuit switching element with an external control signal to write data in the memory 4-1 and read data out the memory 4-2. This switching operation is performed instantaneously, so no adverse influence is exerted upon display operation.
