| titleOfInvention | SAR image target detection method based on visual attention model and constant false alarm rate |
| abstract | The invention discloses a SAR image target detection method based on a visual attention model and a constant false alarm rate, which mainly solves the problems of slow detection speed and high clutter false alarm in the existing SAR image sea surface ship target detection technology. The implementation steps are: extract the saliency map corresponding to the SAR image according to the Fourier spectrum residual information; calculate the saliency threshold to select the potential target area on the saliency map; adopt the constant false alarm rate method of adaptive sliding window for the potential target area. Detection to obtain the initial detection results; the final detection results are obtained after eliminating false alarms from the initial detection results, and slices of suspected ship targets are extracted to complete the target detection process. The invention has the advantages of fast calculation speed, high target detection rate and low false alarm rate, and has the advantages of simple method and easy realization, and can be used for ship target detection on the sea surface. |
