相控阵AEW雷达杂波自由度分析
ON CLUTTER DOF FOR PHASED ARRAY AIRBORNE EARLY WARNING RADARS
-
摘要: 自适应抑制机载预警(AEW)雷达杂波的问题近年来受到了广泛关注。有效进行自适应处理的必要条件是系统可控自由度数大于杂波自由度数。本文详细研究了相控阵AEW雷达的杂波自由度问题,得到了一些新结果。这些结果有助于设计自适应系统。Abstract: In recent years, adaptive clutter suppression for airborne early warning (AEW) radars have attracted considerable attention. A necessary condition for efficient clutter suppression is that the number of adaptive degree of freedom (DOF) is greater than the number of clutter DOF. This paper analyzes DOF of clutter for phased array AEW radars. The new results obtained are helpful to design a adaptive , system for clutter suppression.
