摘要
基于最小二乘滤波精度分析的解析表达式,得出了最小二乘滤波器记忆长度的优化方法,提出一种目标运动加速度的在线实时估计方法,据此可实现最小二乘滤波器记忆长度的实时优化,形成一种适用于机动目标的基于最小二乘的自适应滤波方法。最后进行数值仿真,验证理论分析与算法的正确性。
With the derived expressions for the performance analysis of least squares filtering, an algorithm, by whicli the acceleration of the target can be real- time estimated, is proposed. With tiffs algorithm, the data length of finite memory can be real- time calculated and applied to the least squares filter, thus a kind of adaptive filter based on least squares can be realized. Compoter simulations are made to verify the proposed adaptive least squares filtering algorithm and the expressions for performance analysis.
