Localizing an RF Transmitter using Received Signal Strength

This poster details work conducted by student researchers in the Electrical and Computer Engineering Robotic Department's Swarm Control Lab. Localization of RF transmitters has been attempted using various means and computational algorithms to achieve the most accurate estimates of a source's location in noisy systems. We examined a method proposed by F. Koo and J. Cha to test these algorithms using the received signal strength at multiple receiver locations. The theory behind Koo and Cha's method was found to be compatible with our desired hardware and application in aquatic sensory drift nodes. Preliminary measurements and simulations yielded positive results, further supporting the adoption of this method in RF localization.
