成果介绍

根据本发明实施例公开的一种基于不确定先验知识的降维稀疏STAP方法及装置，利用离散傅里叶变换对雷达接收信号进行一阶降维，得到杂波一阶降维稀疏测量模型；基于不确定的雷达参数先验知识构造二阶降维矩阵，并通过二阶降维矩阵对杂波一阶降维稀疏测量模型进行二阶降维，得到杂波二阶降维稀疏测量模型；基于杂波二阶降维稀疏测量模型构建杂波子空间优化问题；求解杂波子空间优化问题得到杂波子空间，并通过杂波子空间计算STAP滤波器的权重矢量。通过本发明的实施，对杂波稀疏测量模型进行二阶降维，并设计STAP滤波器权矢量以避免矩阵求逆运算，有效降低了滤波器设计的计算复杂度，提高了在机载雷达的杂波抑制上的实现性。
