| 摘 要： | 针对地形辅助导航系统中的地形匹配计算问题,提出一种增强型平均绝对差(MAD)算汉.算法采用最近时刻的位置偏差信息计算当前搜索区域中的高程匹配序列,使系统在任意时刻均可获得当前的地形匹配值,保证了匹配计算的连续性.在此基础上,根据MAD相关系数对数字地图上各搜索点的位置信息进行融合计算,以获取最佳的匹配点.为降低计算冗余量,在重叠的搜索区域对算法进行了优化.另外,当地形特征不明显时引入了判决机制,以增强算法的稳定性.仿真结果表明算法具有较好的动态定位效果. |

| Abstract: | To consider the problem of terrain matching in the terrain aided navigation system,an intensified Mean Absolute Difference(MAD) algorithm was presented.The information of recent location offsets was used to calculate the elevation matching sequences in current searching area,so the current values of terrain matching could be obtained at any time.The continuity of matching calculation was ensured.Based on this method,the position values of all searching sites in the data map were fused according to the MAD c... |
