Methods for validating computer simulation models of missile systems

An overview of simulation model validation methodology is presented, with emphasis on how these techniques may be applied in the missile simulation environment. Because many missile simulations produce an output time series that must be matched to corresponding flight or other laboratory test data, the primary focus is on time series methods. Univariate spectral analysis and cross-spectral analysis techniques useful in simulation model validation are described. Two examples of the use of spectral analysis in validation computer simulation models are given.
