地形匹配技术是一种全天候的自主式辅助导航手段,在航空和民用领域都有着广泛的应用.例如,在导弹飞行过程中,采用地形匹配技术辅助惯性导航系统,可以得到更加精确的定位结果.目前巡航导弹所采用的算法是基于单一路径地形高程序列的;但是单一路径地形匹配算法的定位精度较低,并且需要较长的定位距离和时间.提出了基于激光雷达的多路径地形匹配算法,综合利用多条路径的高程信息,可以大大提高定位的速度和精度,缩短定位距离;仿真结果验证了结论的正确性.

The technology of terrain contour matching(TERCOM)is widely used in the aviation and civil application.For example,if a missile use the terrain contour matching aided navigation system,it can get a more precise position.At present,most algorithm of TERCOM is based on the height sequences of single path,but the precision of this algorithm is low,and it needs long distance and long time to determine the position.This paper puts forward a new algorithm of multi-path terrain contour matching based on laser radar.This algorithm uses information of height sequences of multi paths,which can greatly improve the speed and accuracy of positioning in much shorter distance.The result of simulation verifies the conclusion.
