| Abstract: | Aiming at the disadvantages of phase unwrapping methods for the Goldstein branch cutting and ant colony optimization, a new phase unwrapping algorithm with hybrid particle swarm optimization algorithm (H PSO) is proposed. At first, the residues were divided into dipoles, border points and inner points by preprocessing, and then, the inner points were separated in several areas, where the shortest paths were generated by the H PSO, finally, the shortest paths were segmented into some small branch cuts with the balance charges, and the border points and the disconnected residues were connected with window expanding method. The experimental results show that the algorithm proposed is much better than the classical phase unwrapping method of Goldstein branch cut. |
