Sparse Reconstruction and Resolution Improving of Synthetic Aperture Radar using Deconvolution ISTA -- Evaluation of the Effective Resolution --
Masanori Gocho (NICT) AP2021-130
Abstract (in Japanese) (See Japanese page) 
(in English) The image reconstruction process of the SAR is generally implemented by the macthed filterling, but its resolution is constrained by the signal bandwidth of the radar.
In this study, we discuss the resolution improvement of SAR (Synthetic Aperture Radar) using sparse reconstruction and propose a sparse reconstruction method, Deconvolution ISTA, to solve multi-dimensional convolutional probrems.
The proposed method, which is an optimized version of the ISTA for the convolutional problems, can estimate a sparse source signal from an observed signal.
In this paper, we formulate the SAR reconstruction and describe the proposed method, and show the experimental results using an airborne SAR data.
