Title:
UNDERWATER DIRECTION OF ARRIVAL ESTIMATION METHOD AND DEVICE BASED ON UNIFORM LINEAR ARRAY WITH ADJUSTABLE ANGLE
Document Type and Number:
WIPO Patent Application WO/2019/095912
Kind Code:
A1
Abstract:
An underwater direction of arrival estimation method and device based on a uniform linear array with an adjustable angle. Two uniform linear arrays (L1, L2), between which the angle is adjustable, are used, and the sound velocity variable is eliminated by means of the relationship between the angle between the two arrays and the angle of direction of arrival, such that the sound velocity is irrelevant to the final calculation result, thereby improving the estimation precision; in addition, as the angle between the two linear arrays is variable, multiple measurements can be performed by taking different values, and thus, errors can be better eliminated.
