An Accelerated Iterative Shrinkage-Thresholding Algorithm for Real-Beam Scanning Radar Super-Resolution

摘要

Iterative shrinkage-thresholding algorithm (ISTA) is a simple and robust method to realize super-resolution of real-beam scanning radar. However, slow convergence is a drawback. This work proposes an accelerated iterative shrinkage-thresholding algorithm based on Taylor series expansion. Simulation results are presented to validate the effectiveness the validity and high efficiency of the proposed algorithm.
