Application of Modern Spectral Estimation on Validation for Tactical Missile Simulation Model

According to the consistency test between simulation and flight telemetry data, the credibility of tactical missile simulation model can be effectively verified. To achieve consistency test of dynamic performance based on frequency domain and improve the effectiveness of simulation model validation, the modern spectral estimation method is adopted to analyze the spectrum of dynamic performance of tactical missile. And the spectrum estimation consistency test methods and criteria based on statistics are proposed. According to simulation results and analysis to the specific application on tactical missiles, modern spectral estimation can not only overcome the defects of classical spectral estimation, such as low frequency resolution and spectral distortion, but also improve non-stationary and low-SNR signal spectrum estimation. Therefore, the application of this method in the field of model validation can effectively promote the credibility assessment of tactical missile simulation model.
