Aiming at the problem of whether the hypersonic vehicle simulation model is credible, the verification scheme of the hypersonic vehicle simulation model is proposed based on the analysis of the advantages and disadvantages of the commonly used model verification methods. The time-frequency and frequency-domain methods are used to verify the hypersonic vehicle simulation model, and the credibility of the simulation model is obtained. The experimental results show that using time-frequency domain analysis method provides a more effective method and approach for the credibility evaluation of hypersonic vehicle simulation model.
