论文先后讨论了地形轮廓匹配算法、卡尔曼滤波地形辅助导航算法、小波分层算法的原理、特点、适用范围,做了仿真研究,比较了它们的匹配性能和相关特点。
4.Generally speaking , the algorithm of terrain contour matching is adapted to be used in cruise missiles which made fight path prior for that this algorithm is not a real - time system for it makes use of historical terrain data . while kalman filter algorithm is a real - time , rapid calculation system . which is appropriate for pilot or pilotless aircraft
得出,地形轮廓匹配算法使用历史地形数据,实时性差,比较适合事先规划好航迹的导弹使用:卡尔曼滤波的方法有较好的实时性,计算速度快,很适合有人无人驾驶飞机的机动飞行要求;小波分层只是对地形信息做了高低频分解,其本质还是相似性度量算法,但它有效的降低了匹配算法的计算量。

主要研究内容包括:一、总结分析了当前水下导航的常用方法和不足之处,指出基于航位推算的导航方法,存在着最大的问题就是导航误差的积累问题,如果没有修正系统,这种方法很难满足使用要求;其次指出基于声学的导航方法,造价昂贵,导航范围有限,难以满足自主水下航行器大范围导航的需求;二、总结了当前水下地形辅助导航的主要技术路线,一是基于地形高程的匹配方法,这是当前研究的重点;二是基于地形图像的匹配方法,由于缺乏良好的图像传感器,和可用的海底图像地图,目前这种方法还有待研究发展;三、将两种地形高程匹配的常用方法应用到自主水下航行器上:以相关算法为前提的地形轮廓匹配( tercom )方法和以卡尔曼滤波为基础的桑迪亚惯性地形辅助导航( sitan )方法,前者算法简单可靠,但是导航精度不高,后者虽然精度比较高,但存在着算法较为复杂、有可能发散和出现奇异值等问题。
