Three-dimensional (3-D) deformation could be resolved using multitrack Interferometric Synthetic Aperture Radar (InSAR), with the accuracy dependent on the magnitude of multisource errors within InSAR measurements. To improve the precision of 3-D deformation, it is essential to understand the error propagation mechanism and then develop the methodology for reducing error impacts in 3-D decompositi...Show More
Phase retrieval algorithms with a small number of grabbed buckets are very helpful to the phase-shifting interferometer (PSI) required real-time processing, so the algorithms within five buckets are very practical and are given more attention. In the paper, new 4 and 5-bucket algorithms are developed to compensate phase-shift deviation and detector nonlinearity. Numerical simulations and experimen...Show More
