Abstract :
This paper deals with an error analysis of the phase retrieval algorithm combining the minimization method based on global optimization and the iterative method representing the local approach. The method exploits amplitude measurements on two planes placed in different distances from the measured antenna. In the paper, robustness of the algorithm is investigated and according to this some recommendations regarding the method and measurement are discussed.
