| 摘 要： | 针对地磁匹配导航对匹配区适配性研究的需求,提出一种基于分形维数分析地磁匹配区适配性的方法,从原理上分析了分形维数与适配性之间的关系,在几块选定区域的地磁图上分别对分形维数进行了计算和分析,最后在上述选定区域进行了匹配仿真试验.结果表明:匹配仿真试验中所反映的地磁图适配特性与提出的方法分析所得结果具有良好的一致性,分形维数在指示地磁图适配性上具有优良的性能.

| Abstract: | According to the actual requirements of geomagnetism matching navigation,a method was proposed to analyze the matching suitability of geomagnetism map,and the connection between fractal dimension and matching was explained.Then the fractal dimension was calculated in several chosen area,and the matching experiment was done in the chosen area.The result shows: the result of the experiment is consistent with that of the fractal dimension,the fractal dimension is advantaged in indicating the matching suitabili... |
