单一地形特征参量对地形匹配导航区域可导航性的评价存在局限性,导致评价结果不能真实反映匹配区域可导航性的强弱.根据特征信息融合思想及关联度分析方法,通过引入向量关联度,选取地形特征信息统计参量中地形高程标准差、地形粗糙度、地形相关系数和地形信息熵进行融合,并构成地形特征参量集,利用灰色模糊综合决策理论对该特征参量集进行分析,进而提出一种灰色模糊综合决策的多指标评价方法.仿真结果表明:该方法在匹配区域可导航性的综合评价方面具有可行性,对于区域中匹配数量较多且地形高程数据量较小情况下均能做出正确评价,其评价结果可为地形可导航性分析、地形匹配导航区域选取以及航路规划等提供理论依据.
The single terrain eigenvalue has limitations on the navigability evaluation of terrain matching navigation, which leads the evaluation results can not truly reflect the strength of the navigability of the matching region.According to the characteristics of information fusion and correlation analysis, by introducing the vector correlation, The terrain elevation standard deviation, terrain roughness, terrain correlation coefficient and terrain information entropy in the statistical parameters of terrain feature information are selected to merge and form the terrain feature parameter set, and the feature parameter set is analyzed by the gray fuzzy comprehensive decision theory, and then a This method is feasible in the comprehensive evaluation of the navigability of the matching area, and can be used in the case of a large number of matching in the area with a small amount of terrain elevation data Out of the correct evaluation, the evaluation results can provide theoretical basis for the terrain navigability analysis, terrain matching navigation area selection and route planning.
