OBJECTIVE: Develop a consistent physics based approach to replicating the effects of Radio Frequency (RF) Jammers and Emitters across the Information Operations Range (IOR) to support the Joint Live, Virtual and Constructive (JLVC) Modeling and Simulation Federation.

DESCRIPTION: The parametric data and algorithms essential to accurately replicate jamming and radar emitting effects in a simulated, distributed environment are at a very rudimentary level, if defined at all. Especially for newer systems, the parameters of the jamming systems and their effects on targets are not very well known. Furthermore, the algorithms which do exist are largely physics constructs and do a poor job of replicating the real world with all the environmental factors.

Currently, manual operator intervention is required for consistent representation of jamming effects across the federates. If a desired jamming effect is clearly defined by the Navy�s Jammer Techniques Optimization (JATO) group, then there is likely a manual method which could be devised to generate the desired effect. The success in our ability to manually depict jamming effects is highly dependent on the ability of the model to replicate the desired jammer characteristics, replicate the effects on the targeted receiver system(s), as well as how long and how wide spread the effects are. Since execution depends on manual control to achieve a desired jamming effect, the success of replicating the effect diminishes the more complex, wide scale and long term the jamming event is.

RF effects will need to include those induced by the atmosphere and surrounding terrain across the entire electro-magnetic spectrum with each model having complete geometric freedom dictated by the operator. Each model must support many on many at the waveform level with a variety of user defined antenna patterns. Jammer models will need to replicate the effects of EA-6B and EA-18G Tactical Jamming Systems, including Digital Radio Frequency Memory (DRFM) coherent jamming systems, on Integrated Air Defense System (IADS) Radars and RF communication devices. The technical risks for these models should include (1) overcoming the inherent latencies and (2) instantiating real-world RF effects across a distributed, networked test and training environment such as the Information Operations Range (IOR).

In addition, the models should be integrated with High Level Architecture (HLA) devices to replicate jamming effects on IADS and to replicate the effects of IADS on Tactical Jammer Receiver Systems (TJRS) such as the ALQ-218. Model algorithm performance shall not be at risk to inherent latencies of distributed networked test and training environments such as the IOR.

Reusable event architectures, object models and protocols must be capable of supporting the Secure Defense Research and Engineering Network (SDREN) based IOR to integrate Electronic Attack, Electronic Protect and Electronic Surveillance hardware in the loop with threats from various agencies (such as the Missile and Space Intelligence Center) to replicate the interactions between blue jamming platforms and red targets as a Joint Mission Environment Test and training Capability. This will provide a persistent integrated capability that enables rapid formation of realistic, high fidelity combat and adversary operational environments from which to conduct joint EW testing, training and exercise events.

PHASE I: Develop innovative concept design, model key elements and perform detailed analysis to demonstrate feasibility of predicted performance for prototype, distributed physics based EW object models that replicate the effects of jammer and emitter systems on RF receiving systems across a distributed test environment. A validation methodology will need to be developed in support of this demonstration.

PHASE II: Use validated concept design to investigate, analyze and develop prototype high fidelity jammer, radar and communication emitter models and RF receiver models for integration and demonstration with both the Test and Training Enabling Architecture (TENA) and Joint Integrated Mission Model (JIMM). Prototype demonstrations will make use of the validation methodology developed during Phase I.

PHASE III: Engineer the models to support Capability Test Methodologies for distributed testing in a LVC joint test environment to evaluate system performance and joint mission effectiveness across the acquisition life cycle in a realistic joint mission environment. Finalize and transition the technology to appropriate platforms.

PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: Electromagnetic Interference testing of military and commercial devices and capabilities in a distributed test environment.
