The article proposes a lossless compression method for still radar image based on binDCT transformation.

通过程序设计实现了基于整数DCT的无损压缩算法,适用于遥感图像压缩.

In order to extract geo - science information from radar image, texture must be considered besides gray tone.

要想从雷达图像上充分地提取地学信息,仅靠灰度是不够的, 还必须利用纹理.

The radar image of the station therefore looks like a dense collection of bright spots from which the outlines of the space station can be clearly identified.

空间站的雷达图像因此看上去就像是一堆密集的亮点，通过这些亮点，空间站的轮廓线能清楚地识别出来。

The paper works with a binary electronic chart which has extracted the characteristics of coastal edge and a binary radar image which has been zoomed out in electronic chart at real-time.

针对已抽取海岸边缘特征并二值化的电子海图和已提取海岸边缘特征并缩放至海图比例的实时雷达图像进行匹配。
