| 摘 要： | 军事地理信息系统ＭＧＩＳ是地理信息系统的一个子集，它是以与军事目的相关的地理空间数据为特定研究对象的信息系统。军事地理信息系统比民用地理信息系统更强调地形分析的作用，因为地形与各种军事活动紧密相关。如：通过通视分析，步兵可决定部队的隐蔽区，炮兵可决定射吉的盲区等；通过对特定区域地开遥纹理分析，分数维分析，最大信息熵方向分析可作为巡航飞行器地形匹配时地形选择的准则。本文着重针对巡航飞行器地形匹配原理

| Abstract: | MGIS(Military Geographic Information Systems)is a subset of general GIS.Its research aims are focused on spatial geographical data related to military activities. The terrain analysis is more emphasized in MGIS than in civil GIS, because it could provide the military commanders with the valuable information which help them to make use of terrain and make their decisions for various military actions. In this paper, a new concept of direction information entropy of terrain for terrain correlation matching of cruise missile is introduced. Moreover,an optimization criteria for selecting the direction and position of the terrain matching is presented. |
