Efficient Attributed Scatter Center Extraction Based on Image-Domain Sparse Representation

As an efficient way to interpret the measurements of high-frequency synthetic aperture radar (SAR), an attributed scattering center (ASC) model provides concise and physically relevant features of complex targets. However, accurate extractions of ASCs have been heavily penalized by high memory requi...
