Mutil-mode Sensor Characterization

This proposal describes the approach to be undertaken in the implementation and demonstration of innovative system architecture, algorithms, and design concepts for a prototype SAR False Scene generator. Various approaches have been investigated in Phase I of this SBIR program, with a focus on approaches that are consistent with implementations utilizing state-of-the-art technology to provide capabilities against the high chirp rates and bandwidths needed to support the SAR sensor range resolution. Current implementations are limited in their capabilities to produce multiple reflection points due to constraints imposed through the limited flexibility of the architecture. This manifests itself in the complexities of the implementation hardware, and the difficulties experienced in adding reflection points and generating the necessary modulation coefficients to address changes in the sensor waveform. 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, along with the additional efforts required to achieve a fully operational capability.
