Sparsity-Smoothness-Aware Power Spectral Density Estimation with Application to Phased Array Weather Radar

In this paper, we propose a sparsity and smoothness regularized model for the estimation of nonnegative power spectral densities (PSDs) of complex-valued random processes from mixtures of realizations. The proposed model is designed to jointly estimate frequency components of the realizations and th…
