Abstract :
In this paper, numerical simulation on the minimum entropy method is accomplished to show that the autofocusing solution of this method is only a local-region optimal solution in ISAR imaging. In addition, comparisons between the minimum entropy method and other phase compensation methods are also presented to give a better look on the method. Moreover, results of real data ISAR imaging is provided to see the efficiency and advantage of the method.
