- Abstract
Because of using the distribution characteristics of submarine topography of correlation matching operation to estimate the current position, the navigation and positioning accuracy of the underwater terrain matching navigation depends largely on the terrain feature. In order to satisfy the requirements and improve the precision of navigation, the terrain matching area of navigability analysis is essential. The terrain navigability entropy analysis method with terrain information entropy of the alternative matching area, which is less difference even equal, is unable to determine the navigable performance of matching area. The terrain matching area navigation coefficient deriving from the combination of the isotropy parameter and terrain information entropy to measure the navigability of the matching area is proposed. The results show that the isotropic parameter is greater, the greater the navigation coefficient for the matching area with less different information entropy. Meanwhile, the matching area navigable performance is stronger.
