A time domain recursive low pass filtering algorithm based on Kalman filtering theo-ry is analyzed. 分析了一种基于卡尔曼滤波理论的时域递归低通滤波算法。
The algorithm implements stretch processing and narrowband filtering, and achieves digital beamforming by weighting inter-subarrays. 该方法首先对接收信号拉伸处理和低通滤波，然后在子阵间加权实现宽带子阵数字波束形成。
