In this work, a synthetic aperture radar imaging system is evaluated. The acquisition scenario involves a Pulson P440 UWB-radar and a localization system based on stereo-cameras. The main goal of the sensing system is to image areas behind walls. However, since the SAR acquisition is performed by a human operator and considering the positioning errors, our focus is to compensate for these errors by developing an autofocus SAR procedure. Emergency and military are the envisaged applications. The technique proposed in this paper relies on a strong point scatterer and it is validated on both simulated and real-world data.
