Abstract : A study of the effect of various space frequencies of wind on the impact point of the Honest John M50 unguided tactical rocket is presented. The wind profiles were obtained from Fourier series fits to profiles obtained from Jimsphere balloons. High frequencies were truncated in successive steps to arrive at the effect of such frequencies on the impact point of the Honest John, as computed with a five-degree-of-freedom ballistic simulation model. Significant degradation of accuracy can occur when frequencies down to .001 cycle/ft are truncated. (Author)
