The dhow had gone down with them; they were tossing among the rocks and seaweed, so much human drift on the great ocean of Death!

Although Arab mariners clearly plied the Maritime Silk Route, trading on a large scale over great distances,"this is the first Arab dhow discovered in Southeast Asian waters," says John Guy, senior curator of South and Southeast Asian Art at the Metropolitan Museum in New York,"and the richest and largest consignment of early ninth-century southern Chinese gold and ceramics ever discovered in a single hoard."

尽管无疑阿拉伯水手明显定期往返于海上丝绸之路，跨越非常远的距离进行大规模的贸易，纽约大都会博物馆南亚和东南亚艺术馆高级馆长约翰·盖伊说："这是在东南亚水域发现的第一艘阿拉伯独桅帆船，并且这是有史以来在一个单一场所发现的，9世纪早期南部中国最丰富、最大的货物发运。"

While the Chinese are modernizing their submarine force, half their boats are still basically obsolete diesel-electric designs.

In this dissertation, based on the extraction of meaningful polarization information, the polarimetric speckle reduction, polarimetric contrast enhancement, polarimetric classification and ship detection in polarimetric SAR images are systemically studied. During the study, some new concepts and methods are introduced, which are supported by the application to measured Pol-SAR data. The innovations of this dissertation are as follows: 1 A simplified schem is proposed to reduce the complexity of scattering-model-based speckle filtering. 2 Extend the expression of polarimetric correlation coefficient to help distinguishing targets. In addition, introduce the quantized parameters of polarimetric signature so as to show the differentiae in quantity in co-polar power, cross-polar power and shapes of polarization signatures among targets. 3 Define a new parameter of difference degree between targets, which can be used for express the difference between both coherent and distributed scatters.

论文在较系统的研究目标特征量提取方法和特征量所包含的物理意义的基础上，对极化SAR图像降斑、极化对比增强、极化SAR图像分类以及极化SAR图像中海上舰船目标检测等方面进行了研究，并提出了一些新的概念和方法，对实测数据的处理结果表明，这些新的概念和方法对于极化SAR信息处理是有效的，本文的主要创新成果包括以下方面： 1）针对基于预分类的MMSE极化降斑方法实现过程非常复杂的问题，提出了简化方案，并验证了方案的有效性； 2）扩展了极化相关系数的表示方法，这种扩展增强了极化相关系数对目标的区分效果；另外还提出了极化特征图量化参数，可以从量上表征不同目标间相同极化和交叉极化的回波功率差异和极化特征图形状差异； 3）定义了目标间的差异度参数，它不仅可以用于描述相干目标，还可以用于描述分布目标的差别程度。

In a ten-foot dingey one can get an idea of the resources of the sea in the line of waves that is not probable to the average experience, which is never at sea in a dingey.
