%X In this report, the multi-frequency Multi-Task Bayesian Compressive Sensing (MT-BCS) technique is compared with the Single-Task Bayesian Compressive Sensing one (ST-BCS). The comparison shows how the first method, which concurrently handle the multi-frequency data taking into account the relationship between the correlated inverse problems associated to different illumination frequencies, provides better results. Moreover, single-frequency and multi-frequency approaches have been investigated.
