The Near-field Correction Method of the Basic Array Error based on a Single Auxiliary Vector Hydrophone
The basic array error correction method based on a single auxiliary vector hydrophone is proposed for the difficult problem of the basic array error correction and the constraint of the space size of the tank.This method used the single vector hydrophone by precisely correction to implement non-fuzzy joint estimation of the source orientation and the orientation dependence of the basic array amplitude-phase error, and correct the error of the array element location.The method of this paper is applied to the arbitrary array structure, which doesnt exist the local convergence problem of the joint parameter estimation, only needs one-dimensional search for parameters which make the computing time less and can complete online in real-time.At last, the computer simulation verified the effectiveness of this method.
