Application of assistant knowledge to detect and recognize target in SAR imagery

Because of the characteristics of its imaging principle, strong speckle and impacted by background clutter, SAR image is very difficult to be interpreted, especially for the complex military targets. An interactive recognition system framework is proposed in this article which using contextual information, geospatial information and multi-temporal images, etc, as assistant knowledge in the recognition workflow. It can help detecting and recognizing some target which is difficult to be detected and recognized through human vision or automatic target recognition technology alone.
