摘要
地形匹配技术是巡航导弹实现实时定位，提高制导精度的关键技术之一。文章对地形匹配技术的工作原理、作用进行了介绍；根据算法的不同，对地形匹配系统进行了分类；根据在某型巡航导弹地形匹配系统设计中的应用，详细研究了地形轮廓匹配系统，对该系统的基本原理、匹配算法以及系统的特点进行了研究；根据某型巡航导弹地形匹配系统的设计，对地形匹配系统的技术指标进行了分析；最后，进一步说明了地形匹配系统在制导系统中的作用。
Terrain matching is one pivotal technique of cruise missile to achieve the orientation in real time and to improve the guidance precision. The paper introduces the operational principle and the function of terrain matching. Based on the different of arithmetic, the class of terrain matching system is made. Based on the application of one cruise missile, the terrain matching system is designed, in particular the terrain contour matching system is studied, as well as the basic principle, matching arithmetic and characteristics of the system. Based on the design of one cruise missile with terrain matching system, the technique specification of terrain matching system is analyzed. Finally the function of terrain matching system in guidance system is further explained.
