SI2 TECHNOLOGIES, INC — Department of Defense SBIR Phase I: N231-042

Description

SI2 Technologies (SI2), an ARA Company, proposes to enable high data rate beyond-line-of-sight (BLOS) communications on Unmanned Underwater Vehicles (UUVs) by developing a low-profile, wideband active electronically steered array (AESA) to provide Ku- and Ka-band SATCOM links for emerging LEO constellations. During Phase I, SI2 will develop a high-fidelity AESA system model and perform a series of trade studies to identify the optimal approaches to implement the AESA. During the Phase I effort, SI2 will also continue to engage interested parties to explore potential approaches to commercializing the technologies being developed. In the Phase I Option, SI2 will use the model to create a system conceptual design and specification, block diagram and capabilities document for the system solution and validate the approach via prototyping an interlaced aperture couple patch array for Ka band. At the end of the Phase I effort, the SI2 team will have a proven preliminary design for the overall wideband Satcom AESA meeting the specified requirements supported by an experimentally validated system model and trade studies that provide trade-offs between performance and SWaP-C concerns.
