In this report the clutter-rejection performance of a range-ambiguous MTI and doppler-filter system is analyzed. The reduction of correlation time in a range-ambiguous system in general improves the clutter-rejection performance. However, due to the fold over phenomenon, a faraway target has to compete with the near-in clutter hence a higher improvement factor is required. Examples presented here which take into account these effects show that the improvement factor of a range-ambiguous MTI system is slightly better than that of a range-unambiguous system. However the performance of a doppler-filter processor in a range-ambiguous system is worse. Author
