Abstract
In terms of the requirements of the target detection accuracy, real-time and robustness for synthetic aperture radar (SAR) , this paper designs an algorithm for SAR image target detection based on local window. On the basis of conducting the denoising and segmentation processing to the acquired SAR image, this algorithm implements the strategy of fast registration for sub-pixel accuracy, based on SIFT. Meanwhile, it also achieves the target detection by the feature description results of SIFT lowering the dimension, and based on the expectation maximization algorithm of local window. Experimental results show that this algorithm has a better adaptation to the complex background and illumination along with rotation change, achieving an ideal effect of target detection.关键词
