Abstract

Aiming at underwater object detection and accurate direction finding. Azimuth angle estimation method of linear arrays of vector sensors based on complex weight is proposed. Acoustical signal of vector sensors linear arrays is processed by linear weighting and nonlinear Weighting, and both of the beam comings are multiplied as the result of the beam coming function of arrays of vector sensors linear. Simulations indicate an array with vector sensors can achieve a 3 dB improvement if the nonlinear weighting processing defined in this thesis is utilized instead of linear weighting processing. It provides the important basis for research on direction finding of vector sensors linear arrays.
