| 摘 要： | 提出了一种非平稳地形中TERCOM地图匹配性能的估计方法。首先利用地形差分过程研究相关匹配算法度量值的统计特性 ,获得度量值的均值和方差关于地形差分矩的解析表达。然后讨论度量值统计特性与局部匹配搜索截获概率的关系 ,建议用地形差分矩和局部搜索截获概率作为TERCOM地图匹配性能的估计。通过对实际地形的试验 ,说明基于地形差分矩的匹配性能估计方法是有效的。

| Abstract: | A method for estimating the matching performance of TERCOM map under non stationary terrain is proposed.First,the statistical property of measures of terrain matching algorithms is studied through difference process of terrain.The mean and variation of measures are expressed with regard to the moment of terrain difference.Then,the relationship between the statistical property of measures and the probability of partial searching acquisition is discussed.Estimation of TERCOM map performance with the moment of terrain difference and the probability of partial searching acquisition is proposed.Experimental results of real terrain show that the method herein is efficacious. |
