Next generation radar systems will be required to perform multiple missions. Tactical ground based systems will be called upon for supporting air defense with target identification and for air traffic control. The same system will be required to perform hostile weapons locating together with cueing of friendly weapons. ItÂ’s essential that all these missions be accomplished effectively-with a high degree of performance and readiness. Providing the ability for radar system operation in more than a single frequency band enables realizing optimum multi-mission performance. Lower frequencies generally provide superior long range surveillance capabilities while higher frequencies excel for angular accuracy and target discrimination. Sensis Corporation proposes an innovative and practical solution for realizing active phased array systems capable of operating on two distinct frequency bands with uncompromised performance. Our approach is system driven ensuring fulfillment of radar operational requirements while being amenable to performance growth, supportive of high system mobility, readily maintained, and cost effective. In the Phase I program, Sensis made substantial accomplishments in deriving architectures for multi-band active arrays, establishing Transmit/Receive unit requirements and budgets, and developing a dual-band T/R building block concept. For Phase II, Sensis will further advance from the concept stage towards functional demonstration vehicles. Benefit Benefits of the proposed program include: * Active phased array dual-band operation to achieve long surveillance ranges with accurate target track and discrimination from a single radar system. * Minimum size and weight phased array apertures for high mobility, volume constrained applications. * Phased array architectures supporting broad angular coverage and wide operational/instantaneous bandwidths in each of two distinct frequency bands. * High efficiency air-cooled dual-band transmit/receive array building blocks for minimum generator requirement, low system maintenance, and high overall reliability. * Readily accessible T/R electronics for low repair time plus support growth to emerging component technologies. Primary applications for the developed technology are: * Radar systems for military missions and for commercial aviation. * Communication systems including satellite based. * Size and weight capacity limited platforms such as ground mobile, shipboard, airborne, missile, and space based.
