Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 3.5.b.(7) of the solicitation. | Objective: | Define, develop, and demonstrate innovative modeling/simulation approaches and solutions that will allow accurate representation and interactions of Active Electronically Scanned Arrays and other scanning radar technologies in Distributed Training Simulations and networked training systems.
| Description: | The Active Electronically Scanned Array (AESA) is becoming the new hardware standard for modern military aircraft radars. AESA radars have the ability to both rapidly scan for targets and form multiple, simultaneous detection beams, without mechanically moving the antenna. AESA radars can also be employed as a sensor or, in the future, as an electronic attack capability. Current simulation architectures and standards used in flight simulators, constructive simulations, and Distributed Mission Training were constructed around the need to model mechanically scanned radars and are far too slow to interactively represent an electronically scanned antenna. Modern AESAs can manipulate the radar beam significantly faster that current distributed simulation standards and accompanying software/modeling approaches can represent. These current technical approaches cannot model the AESA’s multiple beams and rapid scans in real time, making accurate replication of the AESA interactions with other simulators’ threats, jammers, and computer generated forces impossible. This makes physically accurate interactive training between a simulated friendly system employing AESA radars and a simulated enemy system employing countermeasures, technically challenging. The USAF requires an innovative approach to representing AESA technologies and their interaction with other systems to allow realistic, accurate Warfighter training with these capabilities.
This effort will define and develop innovative modeling approaches and solutions to the problem of accurately representing AESA radars, active phased array radars, and other rapidly scanning radar technologies in interactive training simulations. Specifically, these methodologies should allow physics-based or highly accurate representations of advanced radar jamming systems, especially Digital Radio Frequency Memory (DRFM), as they interact with an AESA system. It should also provide methods that allow the training system to accurately represent an AESA capability for passive detection and direct electronic attack. Explore and develop a system that provides a generic capability to model AESA radars and countermeasures supporting Live Virtual Constructive (LVC) and Distribute Mission operations (DMO) training technologies and networks. Prototype interactive standards and methodologies should be identified which allow realistic distributed training between these systems. The solution should allow interactions between a single AESA radar model and up to 3 simultaneous targets/jammers over a typical training network. The model should respond to changes in the targets/jammers at a minimum rate of 60HZ in a close looped test.
| PHASE I: Identify an innovative approach to solving the problem of modeling AESA radars in distributed simulations. Determine the technical feasibility of modeling an AESA system’s interactions with a threat environment and running the simulation in real time. Develop an initial concept AESA model design or prototype constructive simulation for interactive demonstration and test of the proposed approach. If possible, identify prototype interactive standards for these simulations.
| PHASE II: A prototype system will be developed based on the Phase-I concept and preliminary design. A feasibility demonstration at the end of Phase-II is highly desired.
| PHASE III | DUAL USE COMMERCIALIZATION:
Military Application: Ability to train against advanced threats in a distributed manner.
Commercial Application: Technologies developed for military training systems can support simulations for civilian communications systems and FAA training systems and civilian standards and protocols.
