In order to overcome the problem of step by step searching method in the two-dimensional Fractional Fourier domain
a hybrid algorithm combines chaos optimization method and multi-step Quasi-Newton method is proposed by deriving the first derivative and its fast computation algorithm.And the global convergence of the algorithm is proved and tested.The simulation result indicates that the presented method is preferable than that of direct searching method
chaos optimization algorithm and multi-step quasi-Newton method mixed with direct searching method considering computation efficiency and accuracy.
