摘    要:从随机过程理论出发,深入研究了描述地形形变场的主要特征参数.通过分析和计算,发现地形高程数据的标准差、粗糙度和相关长度分别反映了特定地域内地形的总体起伏、局部变化及领域相关性的强弱,它们对地形匹配区的选择具有重要意义.在大量实验的基础上,综合考虑系统噪声的影响,构造了一个作为匹配区选择准则的函数.它在实际运用中取得了良好效果.

关 键 词:地形匹配,相关长度,粗糙度,准则函数

Abstract:he major characteristic parameters describing a variable terrain area are studied by employing the theory of the stochastic process. By analysis and calculation, it is found that the standarddeviation, roughness and correlation length of terrain height data reflect respectively the terrain globalwave, local variety adn the correlation of adjacent areas in a specific field and are of great importancefor the selection of the terrain matching field (TMF). Based on a large number of experiments, afunction for the selection criterion of TMF has been constructed with the effect of system noise takeninto consideration. Satisfactory results have been achieved in practice.
Keywords:terrain matching  correlation length  roughness criterion function
