本文是一篇评论几种类型的能提供目标高度和距离、方位的三座标战术对空监视雷达的文章。这些雷达包括采用叠接波束、频扫或相扫以获得仰角覆盖且采用机扫以获得360°方位覆盖的各种雷达。机载雷达和机载武器系统处于近距离时需要三座标雷达。这些近程系统和性能局限的飞机导致对目标高度精度的严格要求。显然,为了引导战斗机去截击敌机,必须同时提供高度信息和距离、方位信息。 This article is an article that comments on several types of three-coordinate tactical air surveillance radars that provide target heights and distances, and azimuth. These radars include a variety of radars with spliced ​​beams, swept or phase sweeps for elevation coverage and machine sweep for 360 ° coverage. Airborne radar and airborne weapon systems require a three-coordinate radar when in close proximity. These short-range systems and limited-performance aircraft result in stringent requirements on the target’s high level of accuracy. Obviously, in order to guide fighters to intercept enemy aircraft, it is necessary to provide both altitude information and distance and bearing information.
