A low complexity algorithm for across range unit effect correction of the moving target via range frequency polynomial-phase transform.

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 target's parameters and estimate the Doppler ambiguity integer, and its computational complexity is low. The simulation results have proved the effectiveness of the proposed algorithm.
