Device for colored indication for radar

Abstract

Abstract PURPOSE:To enable the indication of high brightness of the current and past data through classification by colors by a method wherein the radar data are indicated after the TV conversion. CONSTITUTION:The 1st and 2nd memory control circuits 3 and 4 which are given the address designation by an address signal which a memory control circuit 2 forms in accordance with an azimuth signal from a radar device l are controlled for shifting at every fixed time by a data control circuit 7 and current and past radar video informations from a video signal processing circuit 6 are written in the circuits 3 and 4 overlappingly. These informations thus written in are read out in synchronization with TV synchronizing signals, are turned into colored TV signals through the color modulation corresponding to marker signals by a color signal generating circuit 10 and then are added to a color TV indication device 11. In this way, the observer's own ship 13 and the target ship 14 which are moving are indicated, including the tracks based on the past data, by a prescribed color with high brightness, while a fixed target 15 and the like is also indicated by other color in the same way, thus the observation can be performed easily and surely even in the daytime.
