Abstract :
In order to enhance the performance of the satellite interference geolocation both based on dual satellites systems and triple satellites systems, a new TDOA parameters estimation method were presented based on wavelet denoising and Newman-Pearsom lemma in this paper. By choosing an appropriate wavelet function to process the wavelet transform as weighted calculation, the computation burden can be reduced greatly during wavelet transform. The simulation results illustrated the reliability and effectiveness of this new TDOA estimation method.
