SI2 Technologies, Inc. (SI2) was recently awarded an SBIR Phase II contract to design and develop a wideband, electronically steered multi-beam transmit array for Navy surface ship EW systems. The electronically steered multi-beam wideband array technology used was developed originally for the Navy on another program in 2011, the Next Generation Jammer (NGJ). This wideband technology was leveraged in the Phase I effort to demonstrate a 10:1 bandwidth array with wide instantaneous bandwidth and high efficiency at targeted frequencies. In Phase II, the wideband array concept will be refined through modeling and hardware to a 20:1 bandwidth. During this new program, an antenna demonstrator with integrated wideband RF electronics will be fabricated and tested to demonstrate performance including wideband, wide scan capabilities. The recent award also has an option where SI2 Technologies will perform system level testing to further mature the technology and mitigate risk for transition.
