摘　　要：在回顾现有制导技术之后 ,提出了一种新的导弹制导思想———利用动态DEM匹配方法实现导弹制导。在介绍这一思想及其实现步骤之后 ,文章着重介绍动态DEM匹配阶段中涉及的几个关键环节 ,即特征提取、特征描述、特征匹配、变换参数的解求以及相关匹配的改进等问题 ,最后 ,用实验验证了上述思想 ,得出结论 。This paper deals mainly with the method of dynamic DEM matching. Based on reviewing the current situation of missile guidance, the authors put forward a new idea of missile guidance-- missile guidance helped by dynamic DEM matching, with a description given concerning its idea and its implementation procedure. A lot of key problems of dynamic DEM matching are discussed, such as feature extracting, feature describing, feature matching, and solving of transform parameter. Two experiments are used to prove its effectiveness. It is thus concluded that the idea of dynamic DEM matching is feasible. The suggestion about further research is also made in this paper.
