Multibeam Interferometric Sounding Quality for FM Signals: Modelling and Comparison with Field Data
Résumé
This paper proposes a complete prediction of the noise level on the intereferometric phase difference measurement for bathymetric MBES, including baseline decorrelation and additive noise. This prediction allows to compare the performance of different pulse shapes (FM or CW). The results are compared to simulation and estimations and survey data, confirming their reliability.
