This paper1 presents an accuracy analysis of Time Delay Estimation (TDE) in the passive location system. Firstly, the signal processing model using the information of envelope and phase are presented, respectively. Then the Cramer-Rao Lower Bounds (CRLB) for phase delay estimation is developed. The bound is shown to be inversely proportional to carrier wavelength, and for narrowband signals, independent of the signals bandwidth. Simulation results show that the theoretical analysis is correct… CONTINUE READING
