防空导弹是当今电子技术中最先进的产品之一,它也是大量采用微波器件和分系统的最主要的系统之一。自从第二次世界大战末期开始研制以来,许多系统已获得了改进,几个主要的研制计划已付诸生产并全面部署使用。最成功的、使用最为广泛的系统都采用了半主动雷达制导,特别是采用了连续波半主动自动寻的。在过去的三十年里,已生产了80000多枚连续波导引头以及相应的照射器,这或许就是所有使用的微波硬件中最大的一部分。 Air defense missiles are one of the most advanced products in today’s electronic technology and are also one of the major systems that make extensive use of microwave devices and subsystems. Since the late World War II began development, many systems have been improved, several major research and development plans have been put into production and fully deployed. The most successful and most widely used systems are semi-active radar guidance, in particular the use of continuous wave semi-active automatic search. Over the past 30 years, more than 80,000 continuous wave guides and their corresponding illuminators have been produced, perhaps the largest single part of all microwave hardware used.
