Ultra Wideband Electronically Steered Multi-Beam Array (1000-224)

SI2 Technologies, Inc. (SI2) will leverage our demonstrated expertise in efficient, high power, wideband array design to develop a low-cost, electronically steered multi-beam array for multiple shipboard Information Operations (IO) applications. We will build on prior Navy phased array efforts to extend the performance initially to 1 - 10 GHz, and then to 1-21 and 1-50 GHz with high efficiency at targeted frequencies. We will also investigate an array configuration that will extend the available frequency coverage down to 300 MHz, a range already successfully designed, built and tested utilizing similar array architecture. This approach enables simultaneous generation of multiple beams at multiple frequencies to improve overall system performance. This represents a significant improvement over the currently envisioned single beam dish-based solution. In Phase I, SI2 will develop a 10:1 bandwidth electronically steered multi-beam array, and validate our design and manufacturing approach. In Phase II, we will extend the bandwidth to 20:1 - 50:1, and we will team with an industry partner for transition.
