结合国际电联若干标准,在分析雷达对直接序列扩频(DSSS)系统干扰机理的基础上,对直接序列扩频系统在雷达脉冲干扰的误码率(BER)性能进行了推导,并通过仿真模型对在雷达长脉冲干扰和雷达短脉冲干扰下的误码率仿真分析,得到直接序列扩频系统抗雷达长短脉冲干扰的性能。文中的分析方法和结论对复杂电磁环境下电子对抗的研究有一定参考意义。
Based on the ITU standards, the BER performance of direct sequence spread spectrum (DSSS) systems in radar pulse jamming is analyzed based on the analysis of the interference mechanism of the DSSS system. The simulation results The model is simulated and analyzed in the long-pulse radar jamming and short pulse jamming of radar, and the performance of direct-sequence spread-spectrum system in anti-radar pulse interference is obtained. The analysis methods and conclusions in this paper have certain reference value for the research of electronic countermeasures in complex electromagnetic environment.
