A Mathematical Analysis of the Janus Combat Simulation Weather Effects Models and Sensitivity Analysis of Sky-to-Ground Brightness Ratio on Target Detection.
Abstract
The Janus combat simulation offers the user a wide variety of weather effects options to employ during the execution of any simulation run, which can directly influence detection of opposing forces. Realistic weather effects are required if the simulation is to accurately reproduce 'real world' results. This thesis examines the mathematics of the Janus Weather Effects Models. A weather effect option in Janus is the Sky-to-Ground Brightness Ratio (SGR). SGR affects an optical sensors ability to detect targets. It is a measure of the sun angle in relation to the horizon. A review of the derivation of SGR is performed and an analysis of SGR's affect on the number of optical detections and detection ranges is performed using an unmanned aerial vehicle (UAV) search scenario. For comparison, the UAVs are equipped with a combination of optical and thermal sensors.
