摘要
A new autofocus method for maneuvering targets is proposed. The chirp component of the signal can be obtained by means of exhaustive linear search. The random initial phase terms are evaluated precisely by accumulating all the coherent signals in the low SNR case, and the accuracy of estimating the phase error terms can be improved by iteration. Finally, simulation results measured data verify the validity of the proposed algorithm.
