摘　　要：全球定位系统(GPS)区域映射系统通过对转发器的时延控制,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。讨论系统的单站实现条件。首先给出了单站转发的空域模型,在此基础上对单站条件下的映射关系进行了理论推导,给出了求解的迭代算法。通过理论分析和计算发现:单站转发的条件是苛刻的。GPS area-mapping system could induce the GPS user away from its aim and toward the given wrong area by forming false GPS constellation.This is accomplished through the control on time delay of transmitter＇s jamming signal.By this means,it could induce GPS navigation system to drift away from their destination,thus to realize the protection of important target.The conditions for single transmitter station are studied in this paper.And the space model of single transmitter station is given first,then the mapping relation and the iterative algorithm are discussed.Theoretical analysis and calculation results indicate that the conditions for single transmitter station are quite harsh and rigorous.
