HomoR-CS: A homogeneous region-based compressed sensing method for SAR tomography

International Journal of Applied Earth Observation and Geoinformation
The performance of most existing tomographic synthetic aperture radar (SAR) (TomoSAR) methods that reconstruct the scene pixel-by-pixel is degraded by speckle noise and low signal-to-noise ratio. To solve these problems, we propose a homogeneous region-based compressed sensing (HomoR-CS) method for SAR tomography.
