Conference on algorithms for Synthetic Aperture Radar Imagery XVII
作者: Chen, Zhaofu Tan, Xing Xue, Ming Li, Jian Univ Florida Dept Elect & Comp Engn Gainesville FL 32611 USA
We introduce a maximum a posteriori (MAP) algorithm and a sparse learning via iterative minimization (SLIM) algorithm to synthetic aperture radar (SAR) imaging. Both MAP and SLIM are sparse signal recovery algorithms ... 详细信息

Conference on Airborne Intelligence, Surveillance, Reconnaissance (ISR) Systems and Applications VII
作者: Cheng, Beato T. Goodrich ISR Syst Chelmsford MA 01824 USA
A pushbroom MSI sensor collects image data from the ground, parallel to the flight path, at a specific point angle. Images taken at two instances of time while the scanner moves with the platform usually have a spatia... 详细信息
