【摘要】 针对预警机雷达信号,提出了一种递推式空时二维自适应处理方法。此方法采用改进的随机梯度递推算法,不需要计算杂波协方差矩阵及其逆矩阵,保留了系统自由度。仿真结果表明此方法具有较快的收敛速度,滤波性能较好,便于实时处理等特点。更多还原

【Abstract】 For AEW radar, a new space-time adaptive filter with recursive algorithm has been proposed. The recursive algorithm with M-LMS has been adopted;the covariance matrix of clutter and its reverse matrix are not calculated,and the free degree of system is kept. Simulations were presented to show that the filter is characterized by rapidly convergent rate,good performance of filter,and convenient implementation in real time.更多还原
