| 摘 要： | 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。

| Abstract: | The new generation airborne early warning phased array radars will widely adopt flexible multiple-beam so that they will perform multiple functions. This paper presents a new practical STAP approach, which uses multiple-beam architecture and multiple time-delay taps. Moreover, the performance of this approach has been analyzed in detail by comparing with that of recent typical space-time adaptive processing(STAP) approaches. Theoretical analysis and computer simulation show that this method has the low degrees of system, good performance of detecting slow target, strong robustness to error. |
