超宽带引信具有良好的抗干扰性能。为了定量分析超宽带引信的抗干扰性能,基于相关检测方法,分别对跳时调制信号、等间隔信号在不同干扰信号下进行分析和仿真,得出在不同干扰信号下的仿真输出。通过对两种不同发射信号的抗干扰性能的对比,证明跳时调制信号的抗干扰性能优于等间隔信号,经过跳时调制的超宽带信号能够有效提高引信的作战效能。

UWB fuze has a perfect anti-jamming performance. For quantitative discussion on the anti-jamming performance of UWB fuze. The analyses and simulations about the correlation properties between the emission signal and some different interference signals were given in this paper based on the method of correlation detection. The emission signal was about PPM-TH-UWB and the same cycle signal. The simulation about the anti-jamming performance of different UWB signal was given in contrast. The result proves that the anti-jamming performance of PPM-TH-UWB is better than that of the same cycle signal, the PPM-TH-UWB signal advances the operational effectiveness of UWB fuze.
