| 摘 要： | 把卷积盲分离算法应用于雷达系统抗干扰中,提出一种新的雷达系统干扰抑制算法. 该算法在时域中对四阶累积量进行联合块对角化,以实现雷达信号和干扰信号的盲分离. 计算机仿真结果表明,在无噪及含噪情况下,该算法均可把卷积混合的雷达回波信号及干扰信号分离开来,且有很好的分离性能.

| Abstract: | Blind signal separation (BSS) has been used to realize the radar anti-jamming. A new algorithm of radar interference suppression based on convolutive BSS is proposed and the radar performance is improved. Through the joint block diagonalizaton of fourth-order cumulant in the time domain the separation of the radar signals and the jamming is realized. Simulation results show that the new method has better performance of separation. |
