| Abstract: | Generalized cross correlation is an important technical measure to solve time delay estimation problem. Time delay estimation variance can reach CRLB by using ML weighting. The computer simulation results obtained and real data analysis indicate that a GCC TDE method can ensure high estimation precision when it is used in passive localization systems. Furthermore, the factors which influence passive localization precision are discussed. |
