Navigability Evaluation Method of Terrain Matching Navigation Area

RAO Zhe;ZHANG Jingyuan;FENG Wei;Department of Weaponry Engineering,Naval University of Engineering;  
Single terrain characteristic parameter has some limitations in evaluating the navigability of terrain matching navigation area so that the evaluation results cannot really reflect the navigability of the matching area.For solving the problem,this paper selected the statistic parameters in the terrain feature information including the standard deviation,roughness,correlation coefficient and information entropy by using the characteristic information fusion and correlation analysis method,and introducing the vector correlation degree.The terrain feature parameter set was obtained and further analyzed by the grey fuzzy comprehensive evaluation theory,and then a multi-index evaluation method based on the above theory was discussed.The simulation results indicate that the method is feasible in the matching area navigation and can make the right evaluation in the large number of matching areas and the less arnount of terrain elevation deta under the same area.The evaluation result can provide the theoretical basis for the research and application such as the terrain navigability analysis,selection of terrain matching navigation area and route planning.
