Abstract:

Aiming at the motion feature of the space and near space target, by studying the range migration trajectory and the equivalent motion model, a novel range alignment algorithm is put forword, which is based on the global entropy optimization criterion for solving underdetermined equations. Simulation and experimental results show that it is an efficient algorithm. More important, the random offset error and the high frequency phase error are not introduced, which is the precondition of applying the high resolution imaging method.
