摘要
非均匀环境对空时自适应处理 (STAP)是一个挑战。采用一种先直接数据域 (DDD)STAP后统计STAP处理的非均匀杂波干扰抑制级联算法 ,这种级联算法能有效补偿由DDD算法的空时孔径损失而引起的性能损失。此外 ,还提出了一种新的信号滤除方法 ,它可以用于实际AEW雷达系统的信号滤除。
A new space time adaptive processing (STAP) method combined direct data domain with statistics was presented to suppress clutter and interferer in non omogeneous environment. The new method can effectively compensate the performance loss incurred by the spatial and temporal aperture loss of the DDD approach. Furthermore, a new scheme of target signal filter for real phased array airborne early warning (AEW) radar system was also given. The computation results and MCARM data prove the effectiveness of the proposed method.
