摘要:
该文通过建立伪码调相引信启动概率分析模型,从理论上推导出在噪声调频干扰下伪码调相引信的启动概率,仿真分析了压制性噪声调频干扰对伪码调相引信启动概率的影响。仿真结果表明,增加伪码序列的码长和接收机带宽,减小码元宽度,能够提高伪码调相引信启动概率;增加到达引信接收机的干信比,减小干扰信号带宽和干扰载频瞄准误差,能够降低其启动概率;当多普勒频率小于5 kHz时,它对启动概率的影响很小;随着多普勒频率的增加,它对启动概率的影响变大。该文研究可为引信抗干扰性能评估提供一种方法。
Abstract:
The starting probability of pseudo-random code fuze(PRCF) is deduced under suppressing noise FM jamming by setting up an analysis model of the starting probability.The influence of suppressing noise FM jamming on the starting probability of the PRCF is analyzed by simulation.The simulation results show that the starting probability can be improved by increasing the pseudo-random code period and receiver bandwidth and by minishing the code-element width.The starting probability can be reduced by increasing jamming to signal ratio(JSR) of a reaching receiver and by minishing jamming bandwidth and collimating error of jamming carrier wave frequency.The Doppler frequency leaves a small influence on the starting probability when it is less than 5 kHz,but the influence becomes greater with the increase of Doppler frequency.This study can provide a method of assessing anti-jamming performances of fuzes.
