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...
