为了分析无线电引信遭遇有源干扰时的工作情况 ,对引信的检波输出信号进行了仿真。考虑到输入输出的非线性映射关系 ,采用BP神经网络进行仿真 ,将干扰机的主要变量作为网络的输入变量 ,引信的检波输出信号作为网络的输出变量 ,用实验测得的引信检波信号作为样本对网络进行训练。仿真结果表明此方法是可行的 ,仿真结果令人满意 In order to analyze the working condition when the radio fuze encounters the active interference, the detected output signal of the fuze is simulated. Taking into account the nonlinear mapping relationship between input and output, the BP neural network is used to simulate. The main variables of the jammer are taken as input variables of the network. The output of the detection signal of the fuze is used as the output variable of the network. The experimentally measured fuze detection signal is used as a sample Train the network. Simulation results show that this method is feasible and the simulation results are satisfactory
