Correlation properties of UWB Radar target impulse responses

Abstract

In this paper the time domain responses of UWB Radar signals from scattering targets are analyzed. In particular, the aim of this paper is to investigate the pulse distortion of UWB Radar signals by a scattering object, i.e. how does the scattered signal vary with respect to the Radar signal incident on the object itself. The investigation is performed analyzing the polarimetric responses of different targets (flat plate, sphere). The time domain description (impulse response and pulse preserving capability) of a generic scattering process is mathematically described. Then for verification and application, these prior defined quantities are experimentally measured for two particular targets, a flat plate and a sphere.
