Computer Simulation of Turbulence Induced Pointing Jitter for a Laser Designator
Abstract
The statistics of turbulence-induced, angle-of-arrival fluctuations are formulated and presented in a form suitable for computer calculations of the fluctuation power spectrum for the baseline propagation case of an aperture viewing a point source. It is then shown how these results can be applied to the case of a laser target designator of finite aperture size projecting a slightly divergent beam. Representative computer programming is presented (written in BASIC). A sample case has been run with results presented. The necessary random signal generation and filtering procedures are described to generate each of the two components of the pointing jitter with statistics matching the calculated power spectrum.
