摘要：
Phase unwrapping techniques remove the modulus 2 ambiguities of the wrapped phase. A robust phase unwrapping algorithm is proposed which reduces the probability of generating spurious phase jumps. Simulation results confirm that the new algorithm has better performance than the existing method at a low signal-to-noise ratio.
