脉冲多普勒引信抗干扰性能数字仿真

Numerical Simulation of Anti-Jamming Performance for Pulse-Doppler Fuze

以对脉冲多普勒引信危害较大的阻塞式干扰模式为例,通过数字方法对四种雷达信号波形(等宽等周期信号、随机脉位信号、随机二相码信号、随机脉位随机二相码信号)的抗干扰性能进行了仿真分析,给出了仿真计算结果,为脉冲多普勒引信发射波形的选择提供理论支持和仿真数据。

Anti-blocking interference performance with pulse-Doppler fuze modulated by equal-width equal-period pulse sequence, randomly staggered pulse sequence, random binary phase-code sequence and mixed noise modulation sequence is analyzed. Through numerical simulation, some computed results are provided, which offers a theoretical support for pulse-Doppler fuze waveform selection.
