二维自适应杂波抑制的准最佳处理方法─多波束旁瓣对消法

Suboptimum method of two-dimensional adaptive clutter suppression-multi-beams cancelling method

将部分自适应处理中的旁瓣对消技术应用于机载预警雷达二维杂波抑制的处理，提出了一种二维多波束旁瓣对消的新方法。通过合适地选取辅助波束，使得该方法不仅具有良好的容差性，而且对高低速目标均具有很好的检测能力。计算机仿真结果表明，用该方法处理器性能可逼近最佳，并且，由于该方法对计算量要求大大降低，使其更具有实用性。

In this paper, the sidelobe canceller (SLC) is applied to the two -dimensional clutter suppression for AEW radar, and a new twodimensional multi-beams cancelling method is presented. By properly selecting auxiliary beams, good tolerance and detectability for fast and slow targets are achieved. The results of simulation show that this method has suboptimum performancel however, the computation expense is reduced greatly. These make it have a good prospect for real-time applications.
