Geometric active contour based approach for segmentation of high-resolution spaceborne SAR images被引量：2
《Journal of Systems Engineering and Electronics》2015年第1期69-76,共8页Shaoming Zhang Fang He Yunling Zhang Jianmei Wang Xiao Mei Tiantian Feng 
supported by the National Natural Science Foundation of China(41171327;41301361);the National Key Basic Research Program of China(973 Program)(2012CB719903);the Science and Technology Project of Ministry of Transport of People’s Republic of China(2012-364-X11-803);the Shanghai Municipal Natural Science Foundation(12ZR1433200)
Segmentation is the key step in auto-interpretation of high-resolution spaceborne synthetic aperture radar（SAR） images. A novel method is proposed based on integrating the geometric active contour（GAC） and the sup...

Suppressing azimuth ambiguity in spaceborne SAR images based on compressed sensing被引量：1
《Science China(Information Sciences)》2012年第8期1830-1837,共8页YU Ze LIU Min 
supported by National Key Basic Research Program Project(973 Program)of China(Grant No.2010CB731902)
In spaceborne synthetic aperture radar, undersampling at the rate of the pulse repetition frequency causes azimuth ambiguity, which induces ghost into the images. This paper introduces compressed sensing for azimuth a...

AN EVIDENT SIDELOBE CONTROL METHOD BASED ON NSCT FOR SHIP TARGET IN SAR IMAGES
《Journal of Electronics(China)》2011年第4期419-426,共8页Li Xueying Yin Dong Zhang Rong Wang Kui 
Supported by the National Basic Research Program of China (973 Program) (No. 2010CB731900)
Evident sidelobe on faint ship target seriously affects the accuracy of the target segmen-tation in Synthetic Aperture Radar(SAR) images.To avoid this problem,a novel sidelobe control method based on NonSubsampled Con...
