本文分析了一种特殊多项式微分改进型的最小二乘方法。它保留了文献[1]的优点
同时达到最优估计。分析表明
在不同的平滑位置
只要改变系统工作参数
就能使估计值方差保持最小。文中给出了简单的加权系数和估值误差的计算公式。
An improved least square method for a special polynominal differentiation is analysed in this paper. The method is very useful for linear FM pulse compression radar and sonar systems
capable of obtaining optimal estimation while keeping the advantages of refe-rence. It is shown in the analysis that the only need is to change the system work parame-. ter in order to keep meansquare errors in the minimum range at different smoothed positions. Simple formulas for weight coefficients and estimation errors are also shown in the paper.
