SAR Tomographic techniques have been successfully used for separating the contribution of multiple coherent scatterers lying in the same range azimuth resolution cell. Recently 3-D SAR tomographic techniques based on Compressive Sampling (CS) have been proven very performing in recovering increased resolution tomographic images and hence in estimating amplitude and elevation of multiple scatterers. In this paper we investigate the design of a CFAR detector based on CS, based on a statistical test and allowing to reduce signal misinterpretation due to outliers.

Abstract
SAR Tomographic techniques have been successfully used for separating the contribution of multiple coherent scatterers lying in the same range azimuth resolution cell. Recently 3-D SAR tomographic techniques based on Compressive Sampling (CS) have been proven very performing in recovering increased resolution tomographic images and hence in estimating amplitude and elevation of multiple scatterers. In this paper we investigate the design of a CFAR detector based on CS, based on a statistical test and allowing to reduce signal misinterpretation due to outliers.File in questo prodotto:
