摘　　要：针对传统伪码引信使用相关器时存在插损过大,对前级带通滤波器影响大等现象,提出伪码引信相关器采用双共轭匹配法进行匹配,即设计网络的输入输出匹配电路,使网络的输入端与信源共轭匹配,网络的输出端与负载共轭匹配,这样相关器既能从信源处输入最大功率,又能输出最大功率给负载,在整个信号链路中没有发射损耗,从而可以有效的降低相关器的插损。测试和试验结果证明:该方法可有效的减小相关器的插损,大大的改善了伪码引信的性能。Traditional using of pn code correlator,the insertion loss is too large,and cause a influence on the front-end bandpass filter.To solve this problem,we use the proposed correlator pseudo-code fuze matching with double conjugate matching method,namely the design of network input and output matching circuit,makes the input of network and information source of conjugate matching,the output of the network and the load of conjugate matching,this correlator can input maximum power from the source, and can output the power to the load,there is no emission in the whole signal link loss,which can effectively reduce the insertion loss of the correlator.Test and test results show that this method can effectively reduce the insertion loss correlator,and greatly improves the performance of the pn code fuze.
