Abstract: SI2 Technologies, Inc. (SI2) will design and develop a multi-band active electronically steered array (AESA) for the X/Ku/Ka-band satellite communications (SATCOM) and Ku-band tactical common data link (TCDL) on a vertical take-off unmanned aerial vehicle (VTUAV). By leveraging a novel low cost low profile laminar array architecture, an extremely low profile is achieved while maintain high directivity; this provides stronger links and longer ranges without protruding from the platform's outer mold line. The wide scan capability of the array enables a two aperture solution that will leverage diversity for improved system performance. The proposed array development could potentially provide new capabilities in terms of creating high data rate low probability of intercept (PoI) data links for line of sight (LOS) and beyond line of sight (BLOS) communications. Phase I will culminate in a hardware demonstration of a small-scale array optimized for RF requirements identified by the Navy and interested industry partners.
Benefits: The specific objective of this research is to provide a multi-band directive SATCOM and TCDL antenna for low profile integration on a VTUAV. The resulting AESA technology will have many applications across DoD markets including, but not limited to, high frequency intra-flight data links, Radar and EW. SI2's array technology is inherently low profile enables integration to virtually any location of the platform for optimal field-of-view. SI2 is committed to advancing the state-of-the-art of active electronically steered arrays (AESA) for defense applications. The results of this program will influence future research and be applied to solutions for other multi-beam array needs.
