Delay measurement. From submarine acoustics to oceanic acoustic tomography
Time delay estimation is a central topic in signal processing. Genevieve Jourdain has made important contributions in that field. Her work has been supported by applications in submarine acoustics and ocean acoustics tomography. She has applied her deep expertise in muitipaths propagation to mobile systems communications, I present here a panoramic wiev of the evolution of delays measurement : correlation, time super resolution and pursuit of evolutive close delays, in relations with Genevibve Jourdain work in this domain of research and application.
