摘要
提出一种Monte Carlo方法和均方差算法(MSD)相结合的匹配算法,并将本算法用于地磁匹配导航中。该方法根据惯性导航系统指示的位置从地磁图上提取参考地磁数据,将地磁测量数据进行若干次随机干扰后和参考地磁数据使用MSD算法进行匹配,得到若干个匹配位置,取其均值作为最终匹配位置。仿真结果表明本算法可行。
In the paper an matching algorithm based on Monte Carlo method and mean-square-error algorithm was proposed, and was used in geomagnetic matching navigation. This algorithm extracts reference geomagnetic data from the geomagnetic map around the position indicated by INS, and disturbs geomagnetic measurements randomly for several times. Then, the reference geomagnetic data and the disturbed geomagnetic data are used by mean-square-error algorithm to give a series of matching location. And the final matching location is the mean value of these matching locations. Simulation results show that the algorithm is feasible.
