基于地形熵差和高程绝对差度量的地形匹配算法

An Approach of Terrain-matching Based on Terrain-entropy and Tarrain Absolute Difference

研究了地形匹配辅助导航常用的各种算法，设计出一种基于地形熵差和绝对差度量的地形高程匹配算法来实现地形匹配定位功能，应用于地形跟随/地形回避时得到了理想的结果，达到较高的定位精度，是一种很有实用价值的匹配算法。

The approaches used in TAN were studied and a new approach in this dissertation was designed which based on measurement of terrain-entropy and absolute difference to carry out terrain-matching locating function . Experiments testify that the approach can be quite accurate and shows ideal effect when applied in TF/TA.
