Signal processing for the 1992 barents sea tomography experiment
In August 1992, an acoustic tomography experiment was conducted in the Barents Sea. The objective of this thesis is the development of space-time signal processing algorithms to extract the arrival times of rays and modes for that experiment. The temporal signal processing involves pulse compression...
