为研究等幅连续波小信号对无线电引信干扰机理，开展了无线电引信等幅连续波辐照效应试验。试验结果表明，在等幅连续波辐照下，低频等幅干扰信号与目标多普勒信号并存时，可能导致特定包络特性的目标多普勒信号被淹没，干扰引信的定距判断，从而失去近炸功能。从信号理论的角度进一步分析了小信号的对引信的干扰作用机理。
為研究等幅連續波小信號對無線電引信榦擾機理，開展瞭無線電引信等幅連續波輻照效應試驗。試驗結果錶明，在等幅連續波輻照下，低頻等幅榦擾信號與目標多普勒信號併存時，可能導緻特定包絡特性的目標多普勒信號被淹沒，榦擾引信的定距判斷，從而失去近炸功能。從信號理論的角度進一步分析瞭小信號的對引信的榦擾作用機理。

The paper analyzes the interference mechanism of small signal on FM radio fuze.Through the test,it is discovered that when low frequency continuous interference signal coexists with target Doppler signal,under the radiation of continuous wave,the low frequency continuous wave interference signal will cover the target Doppler signal,which will make the fuze ineffective.The paper further analyzes the interference mechanism of small signal on the fuze based on signal theory,and proves it by simulation test results.
