| 摘 要： | 实际中由于多种因素的存在使得对消性能下降,以最小均方准则下的旁瓣对消原理为基础,详细分析了实际中几种重要的因素对自适应旁瓣相消性能的影响,包括辅助天线中信号分量、主辅通道响应不一致、主辅天线间距的影响,最后通过仿真验证了旁瓣对消性能。结果表明,旁瓣对消系统可以有效地抑制有源干扰信号的影响。

| Abstract: | Many factors cause the descending of antijamming performance.Based on the theory of sidelobe cancellation,several significant influencing factors on adaptive sidelobe cancellation are analyzed in detail,including the signal component in the auxiliary antenna,the disagreement of major and auxiliary channel responses and the distance between major and auxiliary antennas.Finally,simulation validates the cancellation performance,which is valuable in appliance.It shows that the adaptive sidelobe cancellation sys... |
