摘　　要：GPS区域映射系统通过对分布式转发器的时延控制,实现定位区域上的映射关系,使由GPS制导的武器错误定位,偏离原有的目标,从而实现对重要目标的保护[1]。文章首先给出了GPS区域映射系统的基本概念和原理;在此基础上对所加时延解的存在性给出了分析,并提出了简易的时延算法;最后通过求解接收机钟差大小证明了所加时延的合理性,证明了系统的可行性。GPS Area-Mapping system could induce GPS user away its aim toward the given wrong section by forming false GPS constellation.This is accomplished through the control of the time delay of distributed transmitter's jamming signal.By this means,it can induce GPS navigating system to drift away from their destination to protect important target from damage.On this,the value of time-delay has been analyzed in this paper first.Then a simple time-delay algorithmic is presented.The analysis of the receiver clock-offsets has proved the rationality of the algorithmic,which provides the feasibility to the GPS Area-Mapping system.
