Estimation of Element Positions in Deformed Uniform Linear Arrays using Received Signals

Position estimation of the antenna elements of a deformed array using received signals is presented. The model considers a uniform linear array (ULA) with a change in the positions of the elements due to deformation of the array. Multiple sources with known direction of arrival (DOA) are used to estimate the position of each antenna element within a certain range. The proposed estimation technique is demonstrated for a deformed array with eight elements under the noiseless and noisy condition.
