摘　　要：为了解决在复杂电磁环境下,破障弹引信识别目标敏感装置信号抗干扰能力差的问题,提出一种将有源滤波和无源滤波组合的滤波电路,抑制破障弹引信与目标敏感装置信号长距离传输时串入的干扰。该滤波电路依据目标敏感装置输出信号、电缆长距离传输时串入干扰信号、有源滤波电路和无源滤波电路的特点及工程的可实现性进行设计。仿真和实验结果表明,相比于单独使用无源滤波电路,组合滤波电路的插入损耗更大,可更有效地抑制电缆束串入干扰,提高了引信识别目标敏感装置信号的可靠性,为破障弹引信滤波电路设计提供了一种新方法。In order to address the issue of poor anti-interference capability of the fuze signal identification for barrier-breaking munitions in complex electromagnetic environments,a filtering circuit combining active and passive filtering was proposed to suppress the interference that was coupled into the signal during long-distance transmission between the fuze and the target-sensitive device.The filtering circuit was designed based on the characteristics of the output signal of the target-sensitive device,the interference signal coupled during long-distance transmission via cable,the features of active and passive filtering circuits,and the feasibility of engineering implementation.Simulations and experiments showed that compared with using a passive filtering circuit alone,the combined filtering circuit had a greater insertion loss and could more effectively suppress the interference coupled into the cable bundle,thereby improving the reliability of the fuze in identifying the signal from the target-sensitive device.This provided a new method for the design of fuzing filtering circuits for barrier-breaking munitions.
