HPM对伪码脉冲无线电引信的压制干扰效应仿真

Barrage Jamming Effect Simulation of HPM with Pulse Radio Fuse Phase-Modulated by M Series

为了对高功率微波作用于伪码脉冲无线电引信的干扰效果进行分析,建立了引信信号处理模型并进行了计算机仿真。仿真结果表明,在频率对准的情况下,当HPM进入引信距离门对回波信号造成压制时,由于HPM的信号频带较宽,覆盖了多普勒滤波器带宽,多普勒滤波器的输出信号幅度仍可达到启动门限电平,压制干扰无效。

For analysis of HPM jamming effect to pulse radio fuse phase-modulated by m series, its signal processing model was established for computer simulation. The simulation result showed that, under the conditions of frequency consistence, if HPM pulse got into the distance gate and suppressed the echo signal, it could cover the Doppler filter by its wide frequency band. Thus the output of Doppler filter also could achieve the threshold level, the barrage jamming had no effect.
