Characterization of Scatterers by their Energetic Dispersive and Anisotropic Behaviors in High-Resolution Laboratory RADAR Imagery

摘要

This paper deals with the energetic analysis of non-stationary scatterers in High-Resolution laboratory radar imaging. A method based on the well-known Multi-Dimensional Time-Frequency Analysis is proposed to extract marginal densities and highlights the frequency and angle (azimuth) signatures associated to a scatterer. Then, basic statistics are processed to characterize the frequency and/or aspect angle signatures. All in all, the efficiency of this technique is demonstrated, in an anechoic chamber experiment. On the one hand, statistics are linked to target characteristics, on the other hand the experiment shows the meaning of parameters and the efficiency of statistics can be discussed.
