Claim 0:
1. A method of efficiently generating a computer-generated forces (CGF) entity that includes a simulated external vehicle to be used within an interactive computer simulation that is displayed within an interactive simulation environment by an interactive computer simulation station, the simulated external vehicle being distinct from a simulated user-controlled vehicle controlled by a user of the interactive computer simulation, the method comprising:
creating an array of state-space model structures having initially unknown parameters that, once known, will define a linearized approximation of a non-linear model of the simulated external vehicle;
generating frequency response matrices by exciting each input-output relationship of the non-linear model of the simulated external vehicle at a plurality of trim conditions using very short Gaussian pulses, wherein the frequency response matrices define a plurality of linear equations;
calculating the parameters by solving the linear equations of the frequency response matrices to thereby provide an array of state-space models that defines the linearized approximation of the non-linear model of the simulated external vehicle; and
generating the CGF entity from the array of state-space models by using controllers to actively cause a return to an unperturbed trim condition and to eliminate spectral leakage without impairing frequency resolution within the interactive simulation environment.
