摘要
MIMO雷达由于其信号与空间多样性带来的目标检测和抗干扰性能优势,成为了雷达研究领域的一大热点,也受到了越来越多雷达对抗研究领域的关注。从MIMO雷达信号侦察模型出发,研究了基于盲信号处理的MIMO雷达对抗系统,采用FastICA算法对空间混叠的MIMO雷达信号进行了盲分离,对MIMO雷达的侦察识别与对抗流程进行了分析,并提出了一种可行的角度欺骗干扰方法,最后给出了若干仿真结果证明该方法的有效性。
MIMO radar as its superior abilities of target detection and anti-interference has attracted more and more attentions of scientific researchers in the field of radar research, and it also has been followed with a lot of interest by anti-radar researchers. Firstly the reconnaissance model and the countermeasure system based on blind signal processing for MIMO radar are investigated. Secondly, the FastICA algorithm is applied to separate space aliasing signals of MIMO radar. Then, the processes of MIMO radar countermeasures are ana- lyzed, and a feasible angle deception interference method is proposed. Finally, some simulations results are performed to show the effectiveness of our methods.
