摘要
作为海洋地球物理导航[1]方法之一的水下地形匹配导航技术正受到各国的强烈关注。文章采用PMF(point-mass filter)算法作为匹配定位算法,利用peaks函数产生模拟数字地图,进行仿真计算,并对计算所得的估计值进行了真实性判断。通过与TERCOM算法的比较,表明该算法具有良好的精确性和鲁棒性。
As one of the marine geophysical navigation methods, underwater terrain matching navigation technology is under intense international attention. In this paper, PMF （point-mass filter） algorithm is selected as a matching localization algorithm. Using peaks function produces a simulative digital map, then judging the facticity of the calculated estimation. Through the comparison with TERCOM algorithm, the PMF algorithm has a good accuracy and robustness.
