摘　　要：针对传统重力辅助导航区域选择方法仅利用单一评价指标所导致的评价结果不全面这一缺陷,提出一种基于模糊决策的多指标综合选取方法。首先,应用该方法计算目标区域重力异常的标准差、粗糙度、相关系数、重力信息熵和重力坡度等表征重力特征的统计参量;然后,利用模糊决策理论方法求解出指标的隶属度矩阵和权阵,得到区域总的评价指数;最后,依据总评价指数进行匹配区选择。仿真结果表明,本方法具有较好的可靠性,评价指数高的区域,其匹配效果更好。Multi-index comprehensive selection criteria based on fuzzy decision theory are developed to improve the incomplete appraisal of traditional selection criteria using the single evaluation index.Firstly, the standard deviation,roughness, correlation, information entropy and gradient of optional areas are calculated.Then, the index membership grade matrix and weight are determined and the total evaluating indicator is given by using fuzzy decision theory. Finally, according to the total evaluating indicator, the matching area selection is conducted.Simulation results indicate that the matching result is better in high evaluating indicator area.
