摘要：Water resources play an important role in region planning, natural disaster, industrial and agricultural production and so on. Airborne SAR images provide advanced means to get water bodies information quickly and accurately because it is not affected by clouds and lights. Water is confused easily with shadow since calm water surface induces mirror reflection when it gives birth to echo wave. Hence its color is similar to shadow so that it is difficult to distinguish between water body and shadow in airborne SAR image. In order to achieve the goal that make distinctions between water body and shadow, the article put forward an innovation that extract water body information from high resolution airborne SAR image based on technique of imaging in different directions and object-oriented
