Radio Frequency/Microwave Hazard Assessment Tool (RHAZ)

The proposed effort will result in the development and demonstration of a preliminary prototype capability for a RF Hazard (RHAZ) assessment tool on a PC platform. The RHAZ tool will be designed to be easy and efficient to use by range safety officers or Base Bio-Environmental Engineers in a deployed environment. The user interface for the RHAZ assessment tool will be modeled in part on the existing Laser Hazard (LHAZ) user interface. A prototype developed in Phase I will demonstrate the efficacy of the RHAZ tool. A variety of computational electromagnetic methods will be investigated for implementation, including simple array theory models, method of moments (MoM), geometrical theory of diffraction (GTD), finite element methods (FEM) and finite difference time domain (FDTD). A combination of selected techniques is anticipated with each selected technique being used as the field solver engine within its respective range of validity.
