Radar Cross Section Pattern Measurements in a Mode-Stirred Reverberation Chamber: Theory and Experiments

This article deals with the ability to perform radar cross section (RCS) pattern measurements within reverberation chambers (RCs). The characterization principle is based on estimation of backscattered field from target at a far-field distance and takes advantage diffuse RC. A frequency sweep scattering parameters achieved in presence absence installed rotating mast, retrieved these measurements. explains underlying theory discusses impact several performances. includes effect stirrer rotation, which enables enhance dynamic range Experiments two different RCs show relevance proposed approach for RCS extraction confirm theoretical analysis.
