When wind field is detected with Dopper weather radar, there are some different size nonecho areas in largescale radar echoes, which lead to great errors when average divergence and average deformation information are extracted. With the technique suggested by Sirmans to simulate the precipitationecho signal, we obtain a plane linear velocity field which includes 0, 1, 2 step overtones and carry on addschirp processing, and then a nearreal Doppler velocity field is generated. Supposing that the special nonecho area exists in the plane linear velocity field and by the use of VAD technology and the repetitive processing, the continuous gap and the noncontinuous gap in the plane linear velocity field would be filled with repetitive processing. The simulation results indicate that for the simulation of nonnoise plane linear velocity field, the nonecho area of continuity accumulation gap from 10° to 180° can be filled inerrably with the repetitive processing in the velocity field. For continuous accumulation gap, under the conditions of σv=2 m?s-1，SNR≥5 dB and SNR=20 dB,σv≤4 m?s-1, and the continuous accumulation gap less than 120°, the nonecho area with the repetitive processing in the velocity field can be filled inerrably. After filling, the absolute errors of 0, 1, 2 step overtones may be controlled to be less than 15%, and the absolute errors of speed controlled less than 30% which is 80 km away from the circle around the gap place iteration. For the plane linear velocity field of noncontinuous accumulation gap from 0° to 180°, under the condition of additional different noise, not only the accumulation gap less than 180° in the plane velocity field can be filled, but also the speed errors can be controlled to be less than 15% which is 80 km away from the circle around the gap place iteration. This shows that the effect and precision are very good when nonecho areas in Doppler wind field are filled with the repetitive processing, and will have a great help for improving the precision of average divergence and average deformation information extracted from the Doppler wind field.
