鉴于新一代机载预警相控阵雷达采用多波束且电子波束灵活可控的特点， 本文提出了一种多波束时域滑窗空时自适应处理方法。理论分析与计算机仿真实验表明， 该方法与现有的几种典型空时二维自适应信号处理 （ Ｓ Ｔ Ａ Ｐ） 方法相比， 具有系统自由度低、低速目标检测性能好、鲁棒性强等优点， 并且实现复杂度较低， 便于工程实现。 In view of the new generation of airborne early warning phased array radar using multi-beam and electron beam flexible controllable characteristics, this paper presents a multi-beam sliding window time-domain adaptive processing method. Theoretical analysis and computer simulation show that the proposed method has the advantages of low system freedom, good performance in low-speed target detection and robustness compared with the existing SSTA methods. Strong, etc., and the realization of lower complexity, easy to implement.
