Synthetic aperture radar imaging pulses

In our work we have demonstrated how techniques that are used to compute fast back-projections can be used in f1 norm regularized LS-based algorithms to make them computationally feasible. The motivation of f1 norm regularization is to promote sparsity in the SAR image where image sparsity is the number of non-zero elements directly in the SAR image or the SAR image projected onto a basis; e.g., a wavelet basis.
