摘要
研究了基于微小卫星的天基干扰,重点分析了转发式欺骗干扰。当采用转发式干扰时,微小卫星对目标星的干扰信号可以看成是多径信号。本文在直接序列扩频体制下,分析了采用转发式干扰的时延选择问题,并基于Matlab Simulink6.5进行了仿真。结果表明当时延接近一个码片时,干扰效果最佳。
Micro-satellite based jamming techniques are studied, and repeating deception jamming is particularly investigated. If repeating jamming is used, the jamming signal from the micro-satellite to the object can be seen as multi-path signal. By using repeating jamming, The jamming delay under direct sequence spread spectrum system is studied, and the simulation results based on simulink are given. The results show that when the delay is about a chip, the jamming effect is the best.
