Research in advanced surveillance systems concepts is actively being pursued throughout DoD. One flexible and cost effective way of evaluating the mission effectiveness of these system concepts is through the use of mission level simulations. This approach enables the warfighter to “test drive” systems in their intended environment, without consuming time and money building and testing prototypes. On the other hand, due to the size and complexity of mission level simulations, the sensor modeling capability can be limited, to the point that significantly different system designs appear indistinguishable. To overcome this we have developed a meta-model approach which permits integrating most of the fidelity of radar engineering tools into mission-level simulations without significantly impacting the timeliness of the simulation. In this paper we introduce the SensorCraft concept and the engineering and mission level simulation tools that were employed to develop and model the concept. Then we present our meta model designs and show how they improve the fidelity of the mission level simulation.
