In single Doppler radar wind retrieval technique there are three methods proposed in recently years, which is VAP, VPP and SVVP method. Three methods were employed to retrieve wind field with the purpose to find out which one is more suitable in practice according their accuracy by using synthetic data and real data. When tests applied with uniform data, the orders of magnitude for relative error of radial velocity is 10^-13 for SVVP, much lower than that of VAP and VPP which both are 10^-4. Furthermore, the results under condition of wind direction unchanged and wind velocity varied linearity with altitude are 10^-8, 10^-3, 10^-3 for SVVP, VPP and VAP, respectively. In real wind field of typhoon "Pearl", the authenticity of surrounding wind and wind shear retrieved by SVVP and VPP is better than VAP, the deviation of simulation would be increased at some points missing data. Relative errors of radial velocity achieved by VAP, VPP and SVVP are 7.02, 5.78 and 3.1 respectively. It indicated that SVVP method's performance is better than that of other two and suitable in practical applications.
