The idea for automatic extraction of the moving target parameters using single-antenna synthetic aperture radar is proposed. The displacements of the target are estimated from the sequence of the single-look SAR images using the Lucas-Kanade optical flow technique. It is shown that both moving target location in the SAR look and its shift direction can be extracted. In addition, the linear road segments are automatically detected from the multi-look SAR image using the Canny edge map and local pixels intensity gradient analysis. Proposed ideas are incorporated into the novel algorithm capable to unambiguously extract the moving target parameters using the single-antenna SAR system. Experimental examples obtained with X-band airborne SAR system are illustrated as well.
