A Suitability Evaluation Method Based on Fractal Dimension in Geomagnetism Matching Navigation

The suitability evaluation has an important influence on suitable-matching region selection of geomagnetism matching navigation. Geomagnetic anomalies have a fractal characteristic. Fractal dimension can describe the self-similar characteristics and subtle changes of irregular, broken, uneven and infinite detail form of geomagnetic anomalies. A comprehensive evaluation function based on fractal characteristics was established, and the ranks of region suitability were gotten finally.
