Based on the moving target detection, this paper proposes a low complexity algorithm for moving target across range unit effect correction on the basis of the range frequency polynomial-phase transform, utilizing which to remove the coupling of the range frequency and the slow time, then the across range unit effect can be corrected effectively. The algorithm does not need to search the targets parameters and estimate the Doppler ambiguity integer, and its computational complexity is low. The simulation results have proved the effectiveness of the proposed algorithm.
