Source localization using random arrays of sensors under multipath fading

This paper proposes a source localization scheme using random arrays of wireless sensors that addresses multipath propagation. Taking advantage of the dominant reflections, the proposed solution finds the location of a signal source by triangulation using the direction of arrival estimations of both the line-of-sight and the reflected components. It uses a space division multiple access, spread spectrum-based receiver to generate the direction of arrival estimates. Simulation results are included to demonstrate that the proposed scheme provides improved estimates by exploiting the non-line-of-sight information.
