Generally,due to the limitation of the dimension of the array aperture,lineararrays cannot achieve two-dimensional(2D)direction of arrival(DOA)*** the emergence of arraymotion provides a chance for *** this paper,a generalized motion scheme and a novel method of 2D DOA estimation are proposed by exploring the lineararray *** be specific,the lineararrays are controlled to move along an arbitrary direction at a constant velocity and snap per fixed time *** the received signals are processed to synthesize the comprehensive observation vector for an extended 2D virtual ***,since most of 2D DOA estimation methods are not universal to our proposed motion scheme and the reduced-dimensional(RD)method fails to handle the case of the coupled parameters,a decoupled reduced-complexity multiple signals classification(DRC MUSIC)algorithm is designed *** results demonstrate that:a)our proposed scheme can achieve underdetermined 2D DOA estimation just by the lineararrays;b)our designed DRC MUSIC algorithm has the good properties of high accuracy and low complexity;c)our proposed motion scheme with the DRC method has better universality in the motion direction.
