Inverse methods involving compressive sensing are tested in the application of two-dimensional aperture-synthesis imaging of radar backscatter from field-aligned plasma density irregularities in the ionosphere. We consider basis pursuit denoising, implemented with the fast iterative shrinkage thresholding ...
