Abstract : Fireline traces generated by manned simulator air-to-air engagements were modeled using two distinct approaches: polynomial fitting of the fireline trace and time series generation of the fireline trace as output with the aircraft dynamics as input. Specifically, the vertical and horizontal components of the bullet in the target plane were modeled using a polynomial in time of from eleventh to thirteenth degree. The time series generation of the bullet trace as output is accomplished by using time-shifted values of the input (aircraft dynamics) as a function space for representation. A least square error fit is accomplished by solving the normal equations by Gaussian elimination. Fit to the data by both methods was satisfactory. (Author)
