Title: X-Band Interferometric Radar (XBIR) for MMR Precision Tracking
Agency / Branch: DOD / ARMY
Contract: W15P7T-04-C-K407
Award Amount: $729,957.00


An X-band interferometric radar (XBIR) system employing digital beamforming (DBF) is proposed to supplement the S-band multi-mission radar (MMR) phased array currently under development by Syracuse Research. This auxiliary X-band array will bolt onto theapproximate 1.5 x 2.0 meter MMR array and provide a precision tracking capability for fire control. The two radars will operate cooperatively in various modes of operation handing off targets between the two radar systems and the fire control system. Thisdual-frequency capability will allow the MMR to realize the long-range target detection and all-weather performance offered by the S-band system with a precision tracking and targeting capability offered by an X-band array.Digital beamforming will be utilized to achieve the full potential of the X-band aperture through the use of dynamic array calibration, adaptive beam shaping, null steering, and improved target tracking. However, significant technical challenges exist inthe design of the X-band antenna aperture, T/R modules and DBF processor. A modular MMIC-based approach will be used and attempts will be made to reduce the hardware cost and complexity. This project will draw upon Applied Radar's on-going X-band DBF andT/R module development for another DoD customer.This array is designed to be used as an auxiliary array for the US Army's Multi-Mission Radar (MMR). A similar array could also be used for the Army's Future Combat System (FCS). The US Air Force is also very interested in DBF technology for largespace-based arrays as well as conformal aircraft and UAV arrays. The Missile Defense Agency (MDA) has also expressed interest in DBF technology for ground-based ballistic-missile detection.
