Based on the fast SAR image matching method,a method combining integrated navigation system(INS) and SAR is proposed for improving the integrated navigation system′s capability.First,the computer version′s SURF (speed up robust feature) method is used to describe the local features of SAR images.Then rapid-index of the interested points is established,and the nearest neighborhood method with the threshold of 0.6 is used during the process of initial matching.Finally,the RSC is used to remove the...
