The proposed method is scalable to a large number of simultaneous channels, and is independent of both the radiating aperture and the radar waveform for modular implementation. The multiplexing network can be readily designed to integrate into FIRST RF's low cost phased array architecture, opening avenues for rapid transition into other development programs for electronic warfare and communications applications, in addition to radar. The phase I program will demonstrate a small array with simultaneous sum and difference beams at C-band using off-the-shelf components, and define an optimal architecture that can be implemented using customized components at X-band during Phase II. The hardware demonstration during Phase I will demonstrate not only the viability of the technical approach, but also the lost-cost and manufacturable nature of the FIRST RF techniques by completing the demonstration with the limited budget and schedule constraints of a Phase I SBIR. Benefits: FIRST RF is proposing a scalable, modular approach to multi-beam phased arrays that does not require the cost, size, and complexity of multiple RF manifolds. This leap ahead in phased array technology will be advantageous in all applications for directive array antennas. For the radar application identified in the solicitation, multiple beams allows for rapid search, classification, and tracking of multiple targets. Other array applications that will benefit from multiple beams include high data-rate line of sight communications for mobile military forces (ground, air, and sea) where multiple beams can increase frequency re-use and network capacity. Multi-function wideband arrays are also being developed to simultaneously support communications, electronic support, and electronic attack functions. A lightweight, cost-effective means for providing multiple beams will significantly increase the capability of those systems and increase the flexibility of platform integration. Commercial MIMO and "smart antenna" communications networks will benefit from a low cost multi-beam array by increasing communications capacity and range in complex environments. Return
