Abstract

This paper presents near-field localization of unintended emitting radio-controlled (RC) sources in a colored noise environment using a uniform linear array antenna. Existing localization methods for RC devices perform satisfactorily under white noise, but they ignore multipath fading or correlation among the sources. Therefore, a suite of novel schemes, referred to as 2-D multiple signal classification (MUSIC)-smooth sparse arrays and 2-D MUSIC-whitened noise, is proposed to bring correlation together among the sources, multipath fading, and color noise effects during near-field location estimation. Experimental evaluation of the proposed methods and the original smooth 2-D MUSIC compares both schemes while demonstrating their effectiveness.
