Abstract:

In order to enhance the performance of interference location for satellite systems based on TDOA Measuremen, a new TDOA parameter estimation method based on Secondary correlation TDOA estimation, combined with improved threshold wavelet de-noising, is presented. By the use of the characteristic of the wavelet de-noising, The algorithm overcomes the limitations of the Hilbert second correlation method which requires a priori knowledge of the signal and noise, able to accurately estimate the TDOA parameters of the signal in the low SNR environment and effectively improve the performance of satellite interference location. The simulation results illustrate the reliability and effectiveness of this new TDOA estimation method for satellite interference localization. © 2012 IEEE.
