本文分析了在激光信息处理装置里滤波方案的重要性及影响滤波精度的各种因素,对于作等速直线运动的目标的距离D(t),本文提出了一个非线性滤波方案。该方案的特点足通过其他途径先得到(?)(t)的精确估计,再把此估计值代入滤波公式,并通过参数最佳化技术,大大减小信息模型的误差,从而显著提高了滤波器的精度。文末还列出了三种滤波方案的计算结果。
This paper analyzes the importance of the filtering scheme in the laser information processing device and the various factors that affect the filtering accuracy. For the distance D (t) of the target which makes the constant velocity linear motion, a nonlinear filtering scheme is proposed in this paper. The characteristic of the scheme is that the accurate estimation of (?) (T) can be obtained by other means first, then the estimated value is substituted into the filtering formula, and the error of the information model is greatly reduced through the parameter optimization technique, thereby significantly improving the filtering Accuracy of the device. The article also lists the results of three filtering schemes.
