Abstract EN
The increase in element spacing can increase the aperture of the array and improve its resolution performance.
However, phase ambiguity will occur when the array element interval is larger than the minimum half wavelength of the incident signal.
The three acoustic velocity components of the acoustic vector are ingeniously constructed into a new kind of quaternions because of the special structure of the acoustic vector sensor array, and the rough estimation of the direction of arrival (DOA) is obtained using the rotation relationship between the subarray steering vectors corresponding to quaternion data.
The rough estimate is used to resolve the phase ambiguity of the spatial phase difference between the array elements, and the high-precision DOA estimation of the signal can be obtained.
Simulation results show that the method is effective.
