Electronic Warfare Environment Simulator System (EWESS)

SPEC proposes to develop an Electronic Warfare Environment Simulator System (EWESS) based on the latest digital synthesis modulation techniques. The hardware-in-the-loop simulator system will be based on SPEC's state-of-the-art Advanced Digital RF Memory(DRFM) Kernel architecture based on its proprietary direct digital synthesis (DDS) coherent modulation core. The Advanced DRFM Kernel architecture's inherent characteristics will provide the EWESS the ability to simulate any radar or communications systemin its frequency range, including those with complex emitter characteristics such as stagger, agile, jitter, pulse Doppler, and other scan types. It will be capable of creating scenarios where many different emitters separated by frequency, time and otherparameters can be simulated. The system will retain the major beneficial operating characteristics of the synthesizer; low cost, sub-microsecond response time, phase coherence, low phase noise and spurious content, high reliability, small size and weightfor airborne or man-portable applications.In the Phase I program, SPEC will work with potential customers to determine required parameters and system performance specifications. Following this, SPEC will determine the key software and hardware componentsthat will interface with the Advanced DRFM Kernel to produce the EWESS. In Phase II, SPEC will build and demonstrate a prototype EWESS.The development of the EWESS will provide the Government with thestate-of-the-art in EW hardware-in-the-loop simulationcapabilities. Thiscapability is critical for the next generation warfighter. The EWESStechnology has immediate application to the digital widebandcommunications market.
