摘要
由于SAR成像机理、强斑点噪声等特点及受分辨率影响,导致SAR图像不直观,特别是对复杂形体小目标的解译相当困难.基于此,文中提供了基于“3S”技术的交互式识别,该方法利用构像方程原理,在“3S”技术(GPS,RS,G IS)和图像数据库的支持下,借助直观的光学图像来识别SAR图上的小目标,以及一些难以判读的大型目标,取得了比较好的识别效果.
Because of the characteristics of its imaging principle , strong speckle and impacted by resolution, SAR image is very difficult to be caught on, especially for the complex small targets. So, a new way of thinking and realization named Interactive Recognition is presented in this article which is based on ＂ 3S＂ technology. The methods use the theory of imaging equation, relying on the ＂3S＂ technology and image database. It can help recognizing some small target and large target which is difficult to be recognized, acquiring good effect.
