海浪杂波对伪码引信的干扰研究

Study of Sea Wave Clutter Jamming to Pseudonoise Code Fuze

针对海面对引信的干扰,分析了海面反射信号的平均功率和平均反射系数,得到不同海情及极化方向上海面反射信号的统计特性。根据海面反射信号的统计特性对该反射信号进行仿真,以检验无线电伪码引信的抗海面干扰能力,并得出结论,无论海面反射信号先于目标回波信号到达引信,还是目标回波信号淹没于海面反射信号当中,都不会影响伪码引信的正常工作。

By being aimed at sea wave clutter jamming to pseudonoise code fuze, the average power and reflective coefficient of sea echo signal were analysed, the statistic characteristic of sea clutter signal was obtained at different sea conditions and polar directions. According to the characteristic, the sea clutter signal was simulated and inputted into pseudonoise code fuse to detect the antijamming abitlity of pseudonoise code fuse. The simulated result shows that sea wave clutter jamming has little influence on pseudonoise code fuse, either sea echo signal arrives in the fuse prior to target echo signal or target echo signal is submerged in sea echo signal.
