Three-dimensional Radar Imaging of a Building

Abstract

This report describes the study of a through-the-wall radar system for three-dimensional (3-D) building imaging, based on computer simulations. Two possible configurations are considered, corresponding to an airborne spotlight and a ground-based strip-map geometry. The report details all the steps involved in this analysis: creating the computational meshes, calculating the radar signals scattered by the target, forming the radar images, and processing the images for visualization and interpretation. Particular attention is given to the scattering phenomenology and its dependence on the system geometry. The images are created via the time-reversal technique and further processed using a constant false-alarm rate (CFAR) detector. We discuss methods of 3-D image visualization and interpretation of the results and point the way to possible future improvements.
