摘要 当存在主瓣干扰时 ,自适应天线方向图会出现副瓣电平升高及主波束变形的严重问题。本文提出了基于阻塞矩阵预处理的自适应波束保形方法和基于特征投影预处理的自适应波束保形方法 ,这两种方法在抑制干扰的同时 ,有效地解决了上述的波束畸变问题。仿真结果证明了这两种方法的有效性。 Under the conditions of mainlobe interference, the adapted pattern suffers much distortion (high sidelobes and distorted mainbeams). An adaptive beamforming based on blocking matrix preprocessing and an adaptive beamforming based on eigen-projection preprocessing are proposed in this paper, which both can reshape the adapted pattern while suppressing the mainlobe interference. The two methods are proven to be effective by the computer simulation results.
