摘要:The linear Weighted Least Squares (WLS) phase unwrapping method, solving the problem in slow convergence rate by iteration method, usually could not easily to get the exact solution. This paper proposes a model of Nonlinear Least Squares (NLS) unwrapping method, which works it out based on the homotopy method. When compared with the classic linear LS phase unwrapping method in real data conditions, this approach verified effective, especially in the noise disturbance areas, which can improve the accuracy of the phase unwrapping.
