In the SAR matching navigation system

the large size of reference image and real-time image

together with the difference in imaging angle

resolution

etc

makes the traditional matching methods can not meet the real-time performance and robustness simultaneously.Comparing various wavelet functions

we select a better one to construct the image pyramid

and realize the real-time performance via a coarse-to-fine matching strategy.The multi-scale circular templates are designed

and fused by the Dempster-Shafer (D-S) evidence theory

achieving the robustness.Evaluation results indicate that the proposed method can accommodate big distortions on the premise of ensuring the matching time.
