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。 Suppression of clutter has been the key technology of Airborne Early Warning (AEW) radar signal processing. Based on the characteristics of the clutter spectrum of the side array of airborne phased array radar, this paper proposes a quasi-optimal method to suppress AEW radar clutter by using time-space two-dimensional matching filtering. The method is characterized by low computational complexity and real- Processing, and detection performance of low-speed targets than the conventional space-time cascade processing has been greatly improved. In addition, this method can also be extended to other non-side-area arrays.
