| 摘 要： | 针对现有地磁匹配基本算法在数据批处理上实时性能的不足和需要预先指定匹配数据序列长度的困难,提出了一种用于地磁导航的迭代评价匹配算法(Iterative evaluation matching algorithm,IEMA)。基于迭代求解思想,将算法时间分散在各个采样时刻,同时采用实时评价方式,在每一步迭代求解后根据实际情况来判断是否可以输出匹配定位结果。试验结果表明,迭代评价匹配算法应用于地磁导航是有效可靠的,并且它能够自适应调整匹配数据序列的长度。

| Abstract: | Basic algorithms for geomagnetic matching have bad real-time performance in data batch processing,and these basic algorithms have to specify the length of matching sequence data in advance.To solve these two problems,the iterative evaluation matching algorithm(IEMA) is presented for geomagnetic navigation.IEMA learns from the iterative idea,which makes the calculation time distribute in each sampling time and IEMA uses real-time evaluation,which can determine whether to output the matching positioning results after one iterative solution.Results show that IEMA is effective and reliable in geomagnetic navigation,and it can adjust the length of matching sequence data adaptively. |
