APPLY MODERN SPECTRAL ESTIMATION METHOD TO VERIFY SIMULATION MODELS FOR ANTITANK MISSILE SYSTEMS

The basic principle of AR Spectral Estimaion and Maximum Entropy Spectral Estimation in the modern spectral analysis and the method of applying the modern spectral estimation to verify simulation models for antitank missile systems are presented in this paper. It is suitable to the singalarity that dynamic process simulation output for antitank missile systems are the short sequences and low signal-to-noise ratio, and aiming at complicated problems of verifying models for antitank missile systems, with the simulative data and flight-test data of rotating and steady antitank missile systems of a type, it is given in this paper that the verifying outcome is attained by the method of modem spectral estimation.
