战术导弹需要使用小型雷达,这向微波工程师们提出了很大的难题.同设计探测舰艇目标的雷达相比,设计探测飞机目标的雷达要困难得多,而设计探测地面目标的雷达最困难.空中拦截用的主动雷达导引头的复杂程度接近现代火控雷达,如F—15战斗机所装备的雷达. Tactical missiles require the use of small radars, which pose a big challenge to microwave engineers, designing radars to detect aircraft targets is far more difficult than designing radars to detect ships, and designing radars to detect ground targets is the most difficult. The complexity of the active radar seeker used in air interception is close to that of modern fire-control radars, such as those equipped by F-15 fighters.
