Localization of Near-Field Radio Controlled Unintended Emitting Sources in the Presence of Multipath Fading
Localization of near-field unintended emitting radio controlled (RC) devices under a multipath environment is considered in this paper using a uniform linear array (ULA). Since received signals are dependent on both angle of arrival (AoA) and distance from the RC devices to the ULA in the nearfield...

description | Localization of near-field unintended emitting radio controlled (RC) devices under a multipath environment is considered in this paper using a uniform linear array (ULA). Since received signals are dependent on both angle of arrival (AoA) and distance from the RC devices to the ULA in the nearfield scenario, traditional localization schemes based on received signal strength indicator, time difference in arrival, which only estimate either AoA or distance, are unsuitable. Therefore, a novel smooth 2-D multiple signal classification (MUSIC) nearfield localization scheme is developed to locate RC devices under a multipath environment with a possible location error of ±0.5 m. Experimental results are provided to show the effectiveness and feasibility of the smooth 2-D MUSIC near-field localization scheme and it is contrasted with other methods, such as symmetric subarray and 1-D MUSIC-based schemes. |
