The knowledge transfer network generates simulated SAR images that is consistent with the spatial distribution of labeled optical remote sensing images and has similar the feature distribution of SAR images, and these simulated SAR images can optimize the SAR ship detection network to improve the generalization ability. The results on the two public datasets of SAR-Ship-Detection-Datasets (SSDD) and AIR-SARShip-1.0 show that the framework effectively improves ship detection performance in the case of small train set, and can significantly reduce the probability of missing alarm and false alarm in detecting complex background images.
