摘　　要：文章从脉冲多普勒引信受界外背景干扰发生虚警的问题出发,基于伪随机脉位与伪码调相复合引信,完成了复合随机调制引信抗界外背景干扰分析。首先根据复合引信系统工作框图和时序图,分析了界外背景干扰回波特性;然后利用自相关函数,定性分析了复合引信抗界外背景干扰性能,并通过仿真计算完成定量分析;最后分析了伪随机调制编码性能对抗界外背景干扰能力的影响。Focusing on false alert caused by background interference beyond unambiguous range,the compound random modulated fuze＇s resistance capacity of background interference beyond unambiguous range based on pseudorandom pulse position modulation and pseudorandom coded phase modulation compound fuze is analyzed.Firstly,the character of background echo beyond unambiguous range by fuze working diagram and time sequence is analyzed.Secondly,the compound random modulated fuze＇s resistance capacity of background interference beyond unambiguous range based on autocorrelation function is analyzed and quantitative analysis is completed by simulation.Finally,the influence of random modulated code on resistance capacity of background interference beyond unambiguous range is analyzed.
