Constructing a mathematical model for a PRA laser hazard assessment

Abstract

A probabilistic laser hazard assessment for air-to-ground laser-target designator operations involves the use of probabilistic functions to estimate the risk of an unprotected observer being inadvertently irradiated by errant laser energy and sustaining a minor level of ocular damage. Evaluation of a Probabilistic Risk Assessment (PRA) model requires the capture of relevant operational, geographic and demographic information together with appropriate system performance data to provide a suitably defined mathematical representation. The outcome is a unique geographic information system designed specifically for air-to-ground laser hazard assessment purposes. These regionally bounded information data and calculations are being encoded in the Military Advanced Technology Integrated Laser hazarD Assessment (MATILDA) utility being developed under a joint program sponsored by United Kingdom, Ministry of Defence (UK MOD) and the United States Air Force (USAF). This paper provides an outline description of the MATILDA mathematical modelling context, which is also designed to accommodate the effect that a contoured terrain may have on the PRA evaluation.A probabilistic laser hazard assessment for air-to-ground laser-target designator operations involves the use of probabilistic functions to estimate the risk of an unprotected observer being inadvertently irradiated by errant laser energy and sustaining a minor level of ocular damage.
