minimum angle

The algorithm is a combination of least angle difference algorithm and adaptive filtering algorithm based on current statistical model,least angle difference estimation is used as the measurement of adaptive filter.

本文针对反直升机雷构成的雷群进行目标定位和跟踪,利用最小角度差算法对目标的位置进行静态估计,用基于“当前”统计模型的自适应滤波算法进行数据处理,最小角度差算法的估计结果作为自适应滤波的观测值;算法简单而且有效,对目标的机动和非机动运动参数都能得到良好的估计结果。
