Abstract
This paper presents a cross-correlated time-reversal algorithm for the reconstruction of UWB radar images. In comparison to a standard backprojection scheme, this algorithm produces images of superior quality with better cross-range resolution. Furthermore, by cross correlating the UWB array channels with a reference channel located appropriately away from the array center, this algorithm can improve the cross-range resolution of the radar images to the pulsewidth of the UWB signal.
