国外试制成功利用彩色电视接收机把陆地和建筑物等固定目标表示为绿色,飞机和船舶等移动目标表示为红色的雷达.以往的雷达都是使用着用残光性荧光体的白朗管的,但因为残光性的衰减很快,所以必须使环境变暗才能观看,有时因观测得不够仔细,还会放跑了移动着的观测对象.但利用彩色雷达,即使过去很难辨认的移动目标也能清晰地看到,因此使雷达观 Foreign trial successfully using the color television receiver to fixed targets such as land and buildings, green, aircraft and ships moving targets such as the red radar.While the past are the use of white light with residual fluorescent phosphor tube, However, due to the fast decay of the residual light, the environment must be dimmed for viewing, and sometimes the observers are not careful enough to run away from the moving object.But using the color radar, even in the past it is difficult to identify the moving target Can also clearly see, so make the radar concept
