abstract

The present work uses the BELLHOP ray tracing model to simulate an acoustic propagation channel in a deep water environment in order to analyze its viability to provide data transmission for monitoring submarine equipment. The simulated scenario is located in the Campos Basin, Rio de Janeiro, on the Brazilian coast, responsible for more than 80% of Brazilian oil and gas production. Temperature and salinity data from five stations were used to calculate the sound speed profiles required to the transmission loss simulations of the acoustic propagation channel. In order to estimate the signal detection capacity according to the medium characteristics, a characterization of the parameters that influence the physical propagation channel was performed. The parameters of three modem models with different operation frequencies were selected and analyzed in order to obtain the Signal to Noise Ratio (SNR) of the transmission signal.
