| 摘 要： | 机载非正侧视阵的近程杂波具有严重的距离依赖性,在距离模糊条件下,现有的空时自适应处理(Space-Time Adap-tive Processing,STAP)算法难以对其进行有效抑制,为此提出了知识辅助的STAP处理方法。通过使用新的样本选择策略,以及改进的针对近程杂波的知识辅助协方差矩阵模型,该方法在处理非正侧视阵近程杂波时的性能接近最优,远高于一般的基于样本估计协方差矩阵的方法,并克服了缺少训练样本的问题。仿真结果证明了该方法的有效性。 |

| Abstract: | The near range clutter of airborne non-side-looking(NSL) arrays severely depends on the range.In the case of range ambiguity,effective suppression is difficult to be carried out by using conventional space-time adaptive processing(STAP) methods.This paper presents a knowledge-aided STAP approach for NSL.By utilization of a new sample selection strategy as well as an improved knowledge-aided covariance estimation(KACE) model for near range clutter,the performance of the proposed approach is close to be optim... |
