Abstract

Abstract:

TDOA estimation of the overlapping signal of multiple chirps with atomic decomposition is studied, and the algorithm for the TDOA estimation of signals based on chirplet atomic decomposition is derived. Using chirplet atomic decomposition, the overlapping signal received directly from the master-receiver can be approached by some chirplet atom dictionary. And then we compute the correlation between each atom and overlapping signal from the slaver-receiver, and search for the peak of correlation. TDOA of every chirp between master-receiver and slave-receiver can be estimated. Simulation shows that the performance of this method is better than that of computing correlation only between signals received by the master-receiver and slave-receiver.

Key words: TDOA estimation, chirplet atom, atomic decomposition, overlapping signal of multiple chirps, passive location
