Indoor THz Synthetic Aperture Radar (SAR) is an emerging research domain. It expands the conventional SAR applications to sub-mm resolution imaging and localization. In general, high resolution is always preferred but it comes with the cost of complexity of the radio front-end chain. Therefore, in this paper three SAR systems with different carrier frequency fc and bandwidth Bw are studied. These systems are set-up with fc= 230/245/275 GHz and Bw= 20/50/110 GHz. The paper presents the comparison between these systems w.r.t. the focused SAR image quality associated with the spatial resolution.
