| 摘 要： | 传统的空时自适应处理算法对空间不同于来向的干扰可以有效地抑制,但对与信号同向的窄带干扰抑制程度不够,同时滤除部分有用信号。对级联IIR陷波滤波器的自适应算法进行了讨论,提出了一种改进的空时处理器结构,将级联IIR陷波滤波器与空时FIR滤波器组相结合。该算法有效抑制了窄带和宽带干扰,改善系统性能,提高输出信干噪比。仿真结果与理论分析相一致,证实了该算法的性能优越性。

| Abstract: | Traditional space-time adaptive processing algorithum can suppress the jams from different directions effectively in which the space is different from signal direction, but it can not suppress the narrowband jams which come from the same direction with the available signal Absolutely in the meantime, it filters part of useful signals. The adaptive algorithm of multistage IIR notch filter is discussed. Then an improved space-time adaptive processor which combines multistage IIR notch filter with space-time F... |
