前言数字式景象匹配区域相关器(DSMAC)是美海军航空电子设备中心发展的一种相关方案,用于常规陆上攻击型“战斧”导弹。图1为典型飞行任务概念描述。导弹中段制导使用惯性导航系统,其导航误差由弹上地形等高线匹配系统(TERCOM)提供的位置修正来限制。末段制导是中段制导的延续,精度由于使用了DSMAC位置修 Introduction The Digital Scene Matching Region Correlator (DSMAC) is a related program developed by the U.S. Naval Avionics Center for use on conventional land attack Tomahawk missiles. Figure 1 shows a conceptual description of a typical mission. Mid-Missile Guidance uses an inertial navigation system whose navigation error is limited by the position correction provided by the Terrestrial Topographic Line Matching System (TERCOM). The last section of the guidance is the continuation of the mid-level guidance, accuracy due to the use of DSMAC position repair
