Abstract

Abstract

Three-dimensional imaging of sea surface altitude is a technology realized with the launch of Tiangong-2. Phase unwrapping is a key step in elevation inversion of three-dimensional radar imaging altimeter. In order to improve the branch cut algorithm proposed by Goldstein, shorten the total length of branch cuts in interferogram and advance the accuracy of phase unwrapping, a method that based on Jonker-Volgenant-Castanon (JVC) global optimal linear assignment algorithm to generate branch cuts is proposed in this paper. At first, all residual points in the interferogram are found out, and the distance between all opposite polarity pairs is calculated. Then, by comparing the distance between each pair of residual points and the distance sum between both of them and the nearest boundary, it is determined whether to place the branch cuts directly between the residual points and the boundaries or to use JVC algorithm. So, the shortest total length of the balanced branch cuts is obtained. The experiments of unwrapping are carried out by using the interferogram both of simulated three-dimensional imaging altimeter sea surface elevation and Etna volcano area. By comparison with the other three algorithms, it shows that the error between the unwrapping result of the proposed algorithm and the real phase value is relatively small. Also, it can void the “islanding phenomenon” effectively.
