Description
Summary:The arrival time determined by vertical array is a useful parameter to apply matched field processing (MFP) methods for source localization. In this paper, the procedure including wavelet transform for extracting the signal, adaptive filter for retrieving the signal, and wigner-vill distribution for determining the arrival time between sensors is presented. During the South China Sea ASIAEX Experiment, the 103 m deep source was towed by a ship. The data receiving system was a satellite–buoy underwater measurement system with a 16-element vertical line array. The experiment showed that the data was collected with very good quality. Results of this procedure are more efficient, and faster than earlier results based on power spectrum for MFP.
