Abstract

A Modified Asymptotic Linear Solver is proposed to estimate emitter locations by solving the intersections of hyperbolas defined by measured time differences of arrivals. The algorithm achieves simplicity and computational efficiency by removing the nonlinearity inherited in hyperbolic localization problems. Off-line parameter optimization is required to minimize the estimation error. Simulation results have shown that performance of the proposed new algorithm is similar to that of a Maximum-Likelihood Estimator in regions of interest.
