Passive source localization employing intersecting spherical surfaces from time-of-arrival differences
Harvey Charles Schau, A. Zed Robinson · IEEE Transactions on Acoustics Speech and Signal Processing · 1987
Problems associated with the use of intersecting hyperboloids for passive source localization from time-of-arrival difference signals are discussed. A closed-form solution for source location is presented given time-of-arrival difference measurements when the distance from the source to any arbitrary reference is unknown.
