雷达

More than 5,000 people are employed by DFS all over Germany. They work at 17 control towers at German airports and six radar control centers as well as the Air Navigation Services Academy in Langen/Hesse and in the headquarters in Offenbach. DFS also has 40 years experience in the planning, development, implementation and operation of air navigation services systems and facilities. DFS Consulting draws upon this knowledge to support and advise its customers.

DFS在德国雇佣85000多名员工，并在德国机场设有17个塔台，6个雷达控制中心，连同在Langen/Hesse的航空导航服务学院和奥芬巴克总部工作，他们在航空导航服务系统和设施的规划、设计、开展、落实、操作方面已有40年的丰富经验，DFS正用这方面的知识为客户们提供顾问服务。

Oilcan is a kind of typical rigid target with big backscattering coefficient, which takes on point figure if the resolution of SAR image is not very high; these point targets to be recognized gather together, and form a target region with some distribution area; the center of the region appears as a beeline, and the speckle noise appears scattered, therefore, considering the different grey distributions between point target and speckle noise region and the space geometry distribution, these point targets can be recognized by this algorithm.

由于在高分辨率情况下，合成孔径雷达图像中油罐个体的散射分别体现为由若干高亮度点围成的椭圆，待识别油罐目标的模糊边缘呈不连续的椭圆状，因此从二值化后的SAR图像中识别出拟目标的不连续边缘，判断其是否满足目标边缘特性来识别出最终结果，采用该方法解决了这类高分辨率下椭圆状目标的识别问题。本文运用了基于Gauss核函数支持向量机的SAR图像典型目标识别方法。
