摘　　要：Moving target detection （MTD） technique is designed to filtering out the clutters. The basis of the MTD digital signal processor is a bank of Doppler filters designed using FFT algorithm. For high pulse repetition frequency （HPRF）, it leads to a long time calculations and great complexity in hardware implementation. Frequency domain detector is represented by Welch method Realized Doppler filters bank which will reduce the time calculation. The proposed method enhances the target detection capabilities by providing higher detection probabilities or lower false alarm rates. The performance of the two systems, the traditional MTD-I and Welch method are compared from the viewpoint of probability of detection （Pd）, probability of false alarm （Pfa）. Computer simulation results are presented to support the superiority of the proposed technique.Moving target detection （MTD） technique is designed to filtering out the clutters.
