| 摘 要： | 地磁匹配导航的实质是数字地图的匹配.地磁数据库的精度和地磁适配区的选择是地磁匹配导航中的2项关键技术.文中把克吕格插值算法引入到地磁图的重构中,仿真结果表明了其有效性;同时把熵选择法和统计特征法引入到地磁适配区的选择中,通过仿真结果对2种方法进行比较,结果表明,熵选择法综合效果更好,更适合于在实际中应用.

| Abstract: | The essential of geomagnetic matching navigation is digital map matching.Geomagnetic data precision and the choice of the geomagnetic adapted district are the key factors which influence the precision of geomagnetic matching navigation.In the paper,the Kriging method is introduced to the technology of reconstruction of geomagnetic map;the results indicate that the Kriging method can increase the resolving power of the geomagnetic map,which is favorable for the geomagnetic matching navigation.The statistical... |
