机载雷达是飞机上各种雷达的总称,主要用于控制机载武器,实施空中警戒、侦察,保障精确的飞行和飞行安全等,它是现代军用飞机的重要技术装备。目前,大多数机载雷达都是军用机载雷达。 世界上第一台机载雷达出现在20世纪30年代的英国。当时,英国为了对付德国的潜水艇,自1935年开始研制雷达,1937年7月进行了首次雷达空中试验,观察海面军舰并协助航行与着陆。1938年,英国研制出最早的机载对海搜索雷达ASV Mark Ⅱ,同时还研制了AI型机载截击雷达。1940年2月,英国研制成功频率为3吉赫、功率为一千瓦的多腔磁控管,使机载雷达进入了微波时代。随后,英国和美国研制出H2S型(100毫米)、H2X(30毫米)微波轰炸雷达,并于1942～1943年先后将其投入使用。
Airborne radar is the general term for various kinds of radars on aircraft. It is mainly used for controlling airborne weapons, implementing air warning, reconnaissance, and ensuring accurate flight and flight safety. It is an important technical equipment for modern military aircraft. At present, most airborne radars are military airborne radars. The world's first airborne radar appeared in Britain in the 1930s. At that time, in order to deal with German submarines, the United Kingdom started to develop radars since 1935 and conducted its first airborne aerial trial in July 1937 to observe the surface warships and assist in navigation and landing. In 1938, Britain developed ASV Mark Ⅱ, the earliest airborne maritime search radar, and developed AI-type airborne interception radar. In February 1940, the United Kingdom successfully developed a multi-cavity magnetron with a frequency of 3 GHz and a power of one kilowatt, bringing the airborne radar into the microwave era. Subsequently, the United Kingdom and the United States developed H2S type (100 mm), H2X (30 mm) microwave radar, and in 1942 ~ 1943 has put it into use.
