Integrated passive electronic signature modeling

It has been observed that electronic devices emit unintentional electromagnetic energy. These emissions can create a passive radio frequency signature that can be used to characterize and eventually detect and identify the device. In support of this concept, the authors have integrated high fidelity models and simulations into a framework used to perform collection feasibility studies of unintentional electronic emissions in relevant detection scenarios. This paper will discuss the elements involved in simulating realistic electronic emissions in a complex environment, including near earth propagation, terrain model effects, and visualization techniques.
