Polarimetric Monopulse Radar Scattering Measurements of Targets at 95 GHz

Abstract : This paper describes a 95-GHz polarimetric monopulse instrumentation radar and Selected scattering measurement results for an armored vehicle. the radar is all-solid-state, coherent, frequency steppable over a 640-MHz bandwidth, and completely polarimetric for linearly or circularly polarized- radiation. Details of the methods used to perform the amplitude and phase calibrations and the effectiveness of polarization distortion matrix corrections are included in the paper. Measurements made with the radar of various vehicles on a turntable have allowed quasi-three-dimensional polarimetric ISAR images of the targets to be generated. Sample images for an infantry combat vehicle are presented together with high-resolution range profiles of the target for all monopulse channels.
