Advanced Techniques for Digital Radio Frequency Memories (DRFM)

This proposal describes the approach to be undertaken in the demonstration of innovative system architectures, algorithms, and design concepts for the development of Advanced Techniques for Digital Radio Frequency Memories (DRFMs). Various approaches will be demonstrated, with a focus on approaches that are consistent with implementations utilizing state-of-the-art technology to provide independent EA/EP capabilities against multiple simultaneous threats. Current implementations are limited in their capabilities due to constraints imposed through the limited flexibility of the architecture. This manifests itself in the difficulties experienced in adding features and capabilities to the current generation of DRFMs employed for the T & E community. Another example of this is the current limitation in generating only one pulse output when the techniques employed may call for multiple overlapping returns. The evolution of developmental sensors to larger bandwidths and frequency agility when using compressed waveforms also drives the focus on real-time implementation and wide bandwidth capabilities. The cost and benefit of the demonstrated approaches will be assessed.
