摘　　要：GPS（Global Position System）区域映射系统通过对分布式转发器的时延控制，可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，进而实现对重要目标的保护。本文针对新一代接收机自适应天线技术，建立了系统空域模型，给出了有效干扰半径。通过本文提出的布阵方法，使得由GPS制导的武器在特定区域内只能接收转发信号，此时控制转发时延实现诱导，否则零陷卫星信号和转发信号，使由GPS制导的武器丧失制导能力，从而实现对重要区域的保护。GPS area-mapping system could induce GPS weapon away from its aim toward the given wrong section by forming false GPS constellation. This is accomplished through the control of time delay of 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. This paper analyzes influence of adaptive nulling antenna to GPS area-mapping jamming system, establishes the mathematic model and gains the formula of area radii. By this means,the GPS navigating systems have to be controlled by the transmitter＇s jamming signal. At this moment, the system could induce GPS navigation weapon by controlling time delay of distributed transmitter＇ s jamming signal. Otherwise, the weapon can not receive GPS signal and jamming signal and its navigation ability is lost. So, the important area would be protected by the system.
