| 中文摘要 | among different phase unwrapping approaches, the weighted least-squares minimization methods are gaining attention. in these algorithms, weighting coefficient is generated from a quality map. the intrinsic drawbacks of existing quality maps constrain the application of these algorithms. they often fail to handle wrapped phase data contains error sources, such as phase discontinuities, noise and undersampling. in order to deal with those intractable wrapped phase data, a new weighted least-squares phase unwrapping algorithm based on derivative variance correlation map is proposed. in the algorithm, derivative variance correlation map, a novel quality map, can truly reflect wrapped phase quality, ensuring a more reliable unwrapped result. the definition of the derivative variance correlation map and the principle of the proposed algorithm are present in detail. the performance of the new algorithm has been tested by use of a simulated spherical surface wrapped data and an experimental interferometric synthetic aperture radar (ifsar) wrapped data. computer simulation and experimental results have verified that the proposed algorithm can work effectively even when a wrapped phase map contains intractable error sources.
