Abstract
Array signal processing schemes can provide accurate estimates for the number of received signal components and their direction of arrival (DoA) at a sensor array. This paper proposes a high resolution framework with multipath mitigation for detecting and locating a signal emitter randomly positioned within a region of interest. First our proposed framework detects the signal of interest and provides the number of line-of-sight (LOS) plus non-line-of-sight (NLOS) components by applying model order selection schemes. Next our approach mitigates the multipaths by exploiting the signal structure and estimating the DoA of each component. Finally, our framework triangulates the estimated DoAs providing the source position. Simulation results are compared to the well known time of arrival (ToA) and DoA based positioning systems illustrating the effectiveness of the proposed framework.
