基于脉内调频的无线电引信信号处理方法

摘要

The application of intra-pulse FM in radio fuze was still immature,a digital singal processing method based on intra-pulse FM was processed.This method used dual-channel,digital mixer and filter,and which was j udged according to the dual-channel signal,exported the execution signal.The simulation results showed that the method could process the echo signal efficiently and accurately.%针对脉内调频体制在无线电引信领域中应用还不够成熟的现实，提出基于脉内调频的无线电引信信号处理方法。该方法采用双通道数字化混频滤波，并对两路多普勒低频信号进行逻辑判别，输出执行信号。仿真计算表明，该信号处理方法能够有效且准确地处理无线电引信基于脉内调频的回波信号，满足引信定距的要求。
