提高匹配制导定位精度的一种数学方法

A MATHEMATICAL METHOD OF INCREASING LOCATION ACCURACY WITH MATCHING GUIDANCE

匹配制导定位是以网格为基准的,减小由此而产生的固有定位误差是研究匹配制导技术所普遍关心的问题。文章从分析匹配定位的相关特性着手,根据匹配相关值函数的连续性,提出一种利用曲面拟合的近似估计方法、经计算机模拟证实,此方法能够较大幅度地减小匹配制导定位误差,是一种提高匹配定位精度的经济、有效的方法。

The mesh is a criterion of matching guidance location. Decreasing its locating inner error is very important In this paper, Correlated characteristic of the matching guidance location is analyzed, first. Then, a approximate method using fitting, of a curved surface is proposed, which is based on continuity of the correlation function, and the results of computer simulation are given. The method can greatly decrease locating error of matching guidance and is effective for increasing matching location accuracy.
