Abstract

The Army Research Laboratory (ARL) has been engaged in an effort to support the "See through the Wall" initiative. As part of the effort, we have explored the possibilities and challenges of using data collected by small groups of men - each man equipped with a small, hand-held, Radio Frequency (RF) sensor - to image the interior of buildings. We examine various multi-static combinations of sensors, especially in configurations that allow for imaging a room from different viewing angles, and we demonstrate the capability of these approaches for providing comprehensive information about a building's interior. We examine the consequences of errors in the assumed position of the RF sensors, and we analyze the effects of the degradation of signal coherence due to mistiming. Simulation results are provided to show the potential of this type of sensor arrangement in such a difficult, urban environment.
