Atmospheric Laser and Infrared Transmission Model

Abstract

This report describes the 2008 version of the Atmospheric Laser and Infrared Transmission (ALIRT) model developed by LMI for the Tactical Air Division of the Office of the Secretary of Defense, Program Analysis and Evaluation. ALIRT is a physical optics model that implements a method for calculating the peak and average fluence delivered to an airborne or ground-based target from a laser weapon on an airborne platform, when the beam propagates through the inhomogeneous, absorbing, scattering atmosphere (refraction and extinction), which is in turbulent motion (turbulence), and when heating of the air by the beam (blooming) may have significant effects. The purpose of the ALIRT model is to support analysis of the use of high-energy lasers and infrared equipment in air combat engagement and campaign analyses.
