Multi-Band Air Defense/Air Search Radar

Next generation radar systems will be required to perform multiple missions. For example tactical ground based systems will be called upon for supporting air defense with target identification and for air traffic control. Additionally the same systemwill be required to perform hostile weapons locating together with cueing of friendly weapons. It is essential that all of these missions be accomplished effectively with a high degree of performance and readiness. Providing the ability for the radarsystem to operate 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 targetdiscrimination. Novel implementations for multi-band radar are essential to support system performance growth and system readiness, and to realize attractive total ownership costs.Sensis Corporation proposes to develop the technologies for realizing multi-band active phased array antennas for high mobility multi-mission radar systems. For Phase I of the proposed program, Sensis will leverage our expertise to formulate the dual-bandradar system operational concept, architect the active phased array, establish key Transmit/Receive channel requirements, and derive an active array T/R building block concept.
