Simulation of Thermal Effects of Microwave Radiation on Warfighters
Abstract
A thermal physiological computer model constructed using MathLab Simulink was adapted to predict the human thermal response to microwave beam radiation. The model simulates soldiers' responses to radio frequency radiation (RFR) from radar, communication and other sources. The model is operational but not complete or completely tested. The model's predictions include core and skin temperatures, skin blood flows, sweat rates, skin moisture, thermal sensation and discomfort. Simulations with the model were compared to human responses measured at Brooks Air Force Base and J.B. Pierce Laboratory from exposures to 100 and 450 MHz RFR beamed at their backs back while seated and wearing shorts. RFR intensities were 8 to 24 mw/sq cm in environments of 28 and 31 deg C. For this frequency range the model assumes the core absorbs the RFR energy. The agreement between model and data was fairly good. It is recommended that this development work continue with comparison testing to human response data measured at higher frequencies. Human simulation capabilities that include thermal effects of microwave radiation could facilitate planning for complex and changing activities and equipment of the modern warfighter.
