| 摘 要： | 为了有效抑制转发式干扰,在采用匹配滤波捕获方法的基础上,提出了基于延迟-等待捕获策略的抗转发干扰P码捕获方法,给出了具体的实现过程,对转发式干扰情况下该方案的有效性和强转发干扰下的局限性进行了理论分析,对有转发式干扰信号场景下匹配滤波P码捕获方案进行了仿真.仿真结果验证了理论分析结果,为军用抗干扰卫星导航接收机的设计提供了参考.

| Abstract: | To suppress the repeater spoofing interferences effectively,a method of acquiring long code based on the match filter arithmetic is proposed by using delay-waiting strategy.The technical implementing process was also presented.Then the effectiveness of the scheme was deeply analyzed in theory when the repeater jamming exists in the environment.The limitation of this method was also investigated in theory in the scene of strong repeater jamming.Simulation on this scheme was carried out with the existence of ... |
