Multibeam Doppler Sonar : Performances in a Oceanic Environment
In a first part, we compte the error due to the geometry (error positionning and mtion of beams). In the experimental work, we perform the correction due to the roll and pitch of vehicle. The problem of "Lever arm" is treated with the subject too. The main parameters for the computation of Dijppler frequency are the beam aperture and the signal to noise ratio. After the experiment, we conclude abaut the error power due to the frequency estimator.
