Due to the critical importance of RF systems working for the warfighter as intended and when needed, the risk of co-site interference must be mitigated. This is especially important for Navy platforms carrying a wide variety of RF systems, such as high-power transmitters co-located with very sensitive receivers. The Navy must ensure that its RF systems are designed, installed and managed with minimal to no self-interference. Conversely, knowing how to precisely and strategically degrade or jam an enemy RF system is of great benefit to the warfighter. Technology which could quickly, automatically, and comprehensively characterize an RF system would be of immediate and significant benefit to the Navy and the warfighter. NuWaves proposes to develop the Rapid Automated Analysis System for Electromagnetic Measurements (RAASEM). The proposal outlines a detailed description of techniques to quickly characterize both transmitters and receivers through non-invasive measurement techniques.
Benefit: Reducing receiver and transmitter characterization time to a fraction of present day allows for the Navy and DoD to more readily address potential EMI and co-site interference resulting from the considerable number of RF systems existing in close proximity. This enhanced capability for rapid measurements is a necessity as there is a clear trend showing an increase in RF systems for any given platform. RAASEM would provide confidence in mitigating co-site interference; permitting crucial RF systems to limit degradation and therefore perform as and when needed. This beneficial capability for managing friendly interference can accordingly also be used to great advantage against enemy RF systems. The DoD and their Prime Contractors delivering RF and Microwave Systems all benefit from this research.
