Aiming at the clutter distribution of forward array, a processing scheme of space-time adaptive processing (STAP) combined with multiple medium pulse repetition frequency (MPRF) is given. The selection of repetition frequency is studied to improve the system performance. The three-way Doppler channel co-processing STAP method in a group of pulse repetition frequency improvement factor and distance / velocity two-dimensional blind zone distribution. Theoretical analysis and simulation results show that this scheme can greatly improve the whole detection performance of airborne forward array radar
