This paper introduces an improved method for TDOA estimation. The time-difference measurement is performed by taking an advantage of the properties of linear frequency modulation signals. According to the performed simulations and experiment results, the proposed TDOA estimation scheme shows good accuracy and thus has the potential to be used in precise indoor location applications.
