摘要
扩频技术的应用已经有几十年的历史 ,将扩频技术应用于雷达引信 ,可使引信具有很多优良性能。介绍了扩频技术的基本原理和主要特点 ,论述了在防空导弹雷达引信上的实现原理 ,给出了一种采用直扩技术的雷达引信的方案 ,详细分析了它的抗干扰性能 ,提出了它的关键技术。
Spread spectrum technology has been used for forty years. It can be applied in radar fuze, which will improve fuzes capability greatly. This paper introduces the basic conception and theory of spread spectrum technology first. Then it disusses the application theory in radar fuze of antiaircraft missile, and devises a radar fuze in application of direct spread spectrum technology. Finally, the paper specifies its capability of antijamming, and presents its key technology.
