Homeland Defense Over-the-Horizon Radar

Summary (Newest Update)

Background The Request for Information (RFI) is issued by the Air Force Lifecycle Management Center, Strategic Sensors Branch, located at Hanscom Air Force Base, Massachusetts. The RFI focuses on the planning, procurement, delivery, installation, integration, testing, and fielding of a complete Over-the-Horizon Radar (OTHR) Receive sub-system as part of an operational OTHR system. The primary mission of the OTHR is to provide long-range sensor coverage of potential threats to North America and integrate data into existing air and missile defense networks. Work Details The contractor will be responsible for managing the entire signal chain from the physical antenna to the delivery of decimated I/Q digital data. Key components include: - A complete 'RF-to-digital' pipeline for the HLD OTHR program. - Receive antenna field grading, cable trenches, and Receive facility preparation. - The provision of Receive shelters in the array field as part of the Receive sub-system. - The system configuration will include one 2-Dimensional (2D) Radar with up to 1700 receive elements. - Interfaces to other sub-systems/services such as Sensor Control and Sensor Network. - Health and Maintenance functionalities including Built In Test (BIT). - The design must accommodate a modular open system architecture with support for future upgrades. Place of Performance The geographic location for performance is primarily in the CONUS Pacific Northwest. Bidder Requirements Vendors must demonstrate experience in designing, fielding, and sustaining HF receiver systems and environmentally controlled shelters. They should also have capabilities to work with third-party systems integrators or contractors as directed by the Government. Additionally, vendors should provide information on Technology Readiness Levels (TRL) and Manufacturing Readiness Levels (MRL) for major components.
