In the SAR image, the road recognition is conducive to the SAR image interpretation using in traffic monitoring, GIS information, and Geographical mapping, but the road is difficult to extract for blurring by speckles. Based on mathematical morphology, a new road extraction method is proposed in this paper. After the pre-processing to reduce the influence of the speckles, the binary image information...
Pose normalization is beneficial for improving the accuracy of Synthetic Aperture Radar (SAR) Automatic Target Recognition (ATR). In fact, pose normalization can be achieved by rotating the given images according to the estimated pose of the target of interest. However, the partial defect targets in SAR images caused by the shadow effect affects the accuracy of pose estimation. This paper proposes...
It presents an approach of moving target detection by multichannel synthetic aperture radar (SAR), which the receivers displaced in heterogeneous arrays. The approach achieves the maximal unaliased band of radial velocities and Minimum detectable velocity, retains full resolution SAR images, the multiple measurement vectors were employed for improvement of the target focusing, and requires no increase...
The rotation angle estimation is useful method to extract the feature of target for the application of SAR-ATR, which would improve the efficiency of the recognition. A novel algorithm based on corner point estimation (CP) is proposed for the target rotation angle estimation in the SAR image, which extracts the feature of corner point information to achieve high precision. In the presented CP method,...
