Doppler velocity simulation and application with SVVP retrieval method

For the VVP (velocity volume processing) wind retrieval method, the problem of an ill-conditioned matrix arising from the coefficients of equations not being resolved, so the method has not been applied adequately and effectively in operation. In this paper, multiple simulated wind field signals with the SVVP (the step-VVP) method are tested. The results prove that the method has the higher precision. An experiment of typhoon ¿Saomai¿ is used to verify the retrieval result, the whole structure of vortex is correct. The simulation and application show that SVVP method is the useful means for retrieval wind of severe weather.
