超宽带脉冲信号对某型雷达的干扰效果仿真研究

摘要

In order to deal with the jamming effect of UWB signal to radar, we simulate the radar receiver and its main signal processing system by Simulink, analyze the characteristics of UWB pulse signals and discuss the PRT of UWB jamming signals as well as the impact of the jamming range change on the jamming effect to a certain type of radar. Results of research show that the jamming effect is better when the PRT is below 22μs, and the shorter the jamming range, the better the jamming effect.%为研究超宽带信号作为干扰源对雷达的干扰效果，对雷达接收机及信号处理主要技术进行了Simulink仿真，对超宽带脉冲信号特征进行了分析，研究了超宽带干扰信号脉冲重复间隔(PRI)以及干扰距离变化对某型雷达干扰效果的影响。研究结果表明，脉冲重复间隔在22μs以下时，干扰效果较好；干扰距离越近，干扰效果越好。
