The proposed system will provide the evaluator with a powerful analysis tool in the determination of the effectiveness of the I/EW system under evaluation in an operational environment. The proposed simulation system will operate using parametric information that has been extracted from an all source I/EW data base. Security entry schemes will be embedded in the tempested IBM PC/AT to provide security of the entire simulation and analysis environment. The proposed system will operate in various scenario configurations that will take into consideration platforms that the system will be deployed on, e.g., ground based, in manned aircraft and/or in UAV's. These scenarios will also take into consideration geometric distribution of emitters with respect to the collection system, fields of view, variations in mixes of both threats and i/ew subsystems, emitter characteristics, environmental dynamics, etc. The propose system will incorporate in the simulation the appropriate measures of technical performance (MOP's) and measures of operational effectiveness (MOE's) that provide the user conclusive results from this simulation.
