SAR tomographic imaging technique based on fusion of the Prony-inspired parametric and MVDR-inspired non-parametric DOA spatial spectral estimators

Abstract

In this paper, the synthetic aperture radar tomography (SARTom) vertical distribution estimation problem is treated within the direction of arrival (DOA) estimation framework. Super-resolution parametric DOA estimation methods improve the vertical resolution and mitigate the effect of sidelobes. Nevertheless, these techniques have the main drawback related… (More)
