Characterization of scatterers by their energetic dispersive and anisotropic behaviors in high-resolution laboratory radar imagery

Abstract : This paper deals with the analysis of energetic non-stationary objects in already focused High-Resolution (HR) laboratory Radar imaging. Energetic non-stationary scatterers are some backscattering variations (azimuthal variations and/or frequency variations) which are linked to the target properties, for example the Radar Cross-Section (RCS). A method, based on Multi-dimensional Time-Frequency Transform and using basic statistics, is proposed to analyze the anisotropy and/or dispersive energetic behaviors of scatterers in the Radar image formation. The efficiency of this technique is demonstrated, in terms of laboratory radar imaging where statistics are lain to characteristics target parameters. For example, the orientation of a scatterer in the case of a directive response.
