Lock-on Ranges of Laser-Guided Systems

Abstract

The thesis is an evaluation of the factors that determine the maximum acquisition and tracking (lock-on) range of laser-guided systems in the military close-air-support mission. The problem is divided into a study of the designed system parameters which are characterized by a clear-air lock-on range, and a study of the effect of the intervening atmosphere. Three model atmospheres are considered: a homogeneous, an exponential, and a three-layer stratified atmospheric aerosol vertical structure. The vertical aerosol number density distribution of a real atmosphere can be bracketed between a homogeneous and an exponential atmospheric model. Conversion charts from clear-air lock-on range to actual lock-on range for the three model atmospheres are plotted.
