摘　　要：抑制杂波一直为机载预警(AEW)雷达信号处理的关键技术。本文根据机载相控阵雷达侧面阵的杂波谱特点,提出了一种用时空二维配对滤波处理来抑制AEW雷达杂波的准最优方法,该方法的特点是运算量小,能实现实时处理,且对低速目标的检测性能较常规的空时级联处理有较大程度的改善。另外,该方法还可以推广到其它非侧面阵的情形。It is the key to suppress ground clutter for airborne early warning (AEW) radars. In this paper, a temporal-spatial nonadaptive joint filtering processing approach is proposed to suppress clutter for AEW radars. The computation load of this approach is small, and the performance for detecting slowly moving targets is better than that of the conventional cascaded nonadaptive processing.
