Error Self-Calibration Algorithm for Acoustic Vector Sensor Array

Algorithm 1

Error self-calibration algorithm for AVS array.

(a) Initialization:

(b) Use the matrix of vector sensor array of amplitude and phase distortion and calculate spectrum of MUSIC algorithm based on formula (10)

and the azimuth corresponding to the spectral peaks of the spatial spectrum is used as the DOA estimation of the signal source

(c) Fix azimuth estimation and calculate from the vector by formula (28)

(d) Compute the cost function value by formula (25) to determine whether the convergence will stop with threshold , and the convergence condition is

if it is convergent, then the iteration stops. Otherwise, , go back to (b).
