Mobilisa and subcontractor Mikros Systems propose to develop the RHAZ analysis tool based on Mobilisa s software package known as AIRchitect®, which already implements several of the key functions required. AIRchitect® was originally developed to model wireless networks onboard US Navy vessels, and incorporates advanced algorithms to simulate RF propagation, model 3D environments and determine ambient RF power levels. The key objective of the proposed program is to modify the baseline AIRchitect® software to provide the additional functionality required for RF hazard analysis. Two types of upgrades will be required. First, the AIRchitect® front-end software, which simulates RF propagation, will be enhanced to support geographical and structural models of the environment, and to incorporate indoor/outdoor RF propagation. Second, additional back-end code will be developed to implement dosimetry algorithms based on applicable standards and methods (such as IEEE C95.1 and the RFR Dosimetry Handbook). User feedback will be provided using color-coded signal intensity maps and recommended safety actions. The RHAZ Analysis Tool will be developed using standard interfaces and modular methods to accommodate a range of dosimetry methods, and will be able to compare predicted results with empirical survey results to validate operation.
