Abstract In order to improve the precision of phase unwrapping in InSAR data processing, a new method is presented based on iterative-weighted greedy algorithm. First, the theory derivation is given in detail. Second, to make the result jump out the local optimization and approach the true phase, an iterative-weigthed greedy algorithm is addressed. Finally, the experiment analysis on simulation data and the real InSAR data verifies the effectiveness of the novel method.
