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,从而偏离原有的目标,实现对重要目标的保护[1]。文章首先给出了求解区域映射系统中虚拟点邻域的迭代算法,在此基础上分析了虚拟点与真实点的位置关系以及转发器的分布对映射比例的影响,并在有效干扰区域内,对如何选择虚拟点的位置和转发器的分布以达到映射比例的优化进行了研究,得出的结论为实际应用提供了参考。
GPS Area-Mapping system induces GPS by forming false GPS constellation, which is accomplished uted transmitter＇s jamming signal. By this means,it can their destination to protect important target from be damag user away its aim toward the given wrong section through the controlling of the time delay of distribinduce GPS navigating system to drift away from ed. An iterative algorithm to calculate the nighborhood of illusive point of Area-Mapping System is pressened. The relation between the real points and illusive points is considered and the effects of the transmitters distribution on the mapping scale are analyzed. The conclusion on optimizing mapping scale by choosing illusive point position and the distribution of transmitters provides reference for practice application.
