A Noncoherent Radar System Approach for Through-The-Wall Imaging

摘要

A noncoherent through-the-wall radar system approach, based on trilateration technique, is presented. This approach involves multiple independent monostatic radar units and as such, provides flexibility in positioning the units with various stand-off distances and inter-element spacing. We demonstrate the proposed noncoherent system approach in an indoor environment using both simulated and real data. The results show that the radar is able to detect and locate multiple targets behind walls.
