Abstract The accurary of geomagnetic matching navigation can be improved a lot in a suitable geomagnetic matching area.Geomagnetic matching area characteristic parameters were analyzed based on statistical association and geomagnetic information entropy,and traditional geomagnetic information entropy was improved,combined with geomagnetic coarseness and accumulated gradient characteristics.Particle Swarm Optimization(PSO)algorithm was employed to obtain the suitable areas.The results show that the geomagnetic matching area improved characteristic parameters reduce runtime largely,and more suitable areas can be selected,which illustrate the efficiency of improved geomagnetic information entropy parameters.
