An Improved Structured-Dictionary-Learning-Based Sparse SAR Imaging Algorithm
Existing structured-dictionary-learning (SDL)-based sparse synthetic aperture radar (SAR) imaging methods suffer from insufficient artifact suppression, limited parameter adaptivity, and inadequate structure preservation during refined imaging under low-sampling-rate conditions. To address these limitations, an improve...
