Potential Discrepancies in Radar Signature Predictions for Ground Vehicles
Abstract
An investigation of modeling issues at Ka-Band and above was conducted using Xpatch, a high-frequency radar signature prediction code based on the shooting and bouncing ray technique. The lessons learned apply to a large class of ground targets of interest for millimeter wave radar applications. We summarize the unclassified modeling results and computational requirements at Ka band frequencies. The ground vehicle simulations indicate that accurate target representations are required to a resolution on the order of the wavelength. In many cases the available data corresponds to near field measurements. In this case we use the Xpatch near-field simulations to better reproduce the measured radar signatures.
