A novel acoustic test bench for evaluating underwater acoustic modems by numerical real-time simulation of the acoustic channel ArchiMer
Arzelies, Patrick; Drogou, Michele; Opderbecke, Jan; Noel, Claire; Beauchene, Serge; Martin, Christophe; Lachaud, Emilie; Nasr, Amin.
This paper deals with underwater acoustic communication, and especially details an innovative approach for off the shelves existing modems performances evaluation. The originality is to be able to predict the operational performances of existing acoustic modems in a real complex situation, without sea trials.

Underwater acoustic noise measurement in test tanks ArchiMer
Cochard, N; Lacoume, Jl; Arzelies, Patrick; Gabillet, Y.
The range capability of underwater acoustic equipment installed onboard underwater vehicles is limited by the noise generated by propellers, hydraulic pumps.,,, Measuring this noise at sea is quite expensive. Here is described a procedure allowing the measurement of the radiated noise in test tanks. This method is derived from techniques previously developed in aerial acoustics and in electromagnetism.
