OBJECTIVE: Develop automated real-time/near real-time spectrum management tools, radio-frequency sensing equipment, algorithms, and/or other technologies that aid Marine radar operators and spectrum planners in spectrum sharing management; and in de-confliction and optimizing radar coverage for United States Marine Corps (USMC) S-band radars operating within congested and contested EM environments.
DESCRIPTION: The S-Band portion of spectrum has unique properties that make it desirable for both military radars and telecommunications industry use, such as 5G. In the Continental United States, the telecommunications industry and Congress are increasingly exerting pressure on the Department of Defense (DoD) to either vacate or share significant portions of S-Band. America’s Mid-Band Initiative for Telecommunications auctioned 3450MHz to 3550MHz to the telecommunications industry. The Emerging Mid-Band Radar Spectrum Sharing initiative directs DoD to study the ability to vacate or share 3100MHz to 3450MHz. Having to share or vacate this spectrum could severely compress the operating space for USMC radars that operate in S-Band. Automated tools and planning aids can help de-conflict spectrum either through deliberate planning or through dynamic spectrum sharing.
Solution requirements include:
- Must take into account geographic and electromagnetic (EM) environments and have the ability to identify conflicts between radar systems and other emitters in the environment.
- An environmental sensing capability shall be automated but also support manual identification and placement of emitters in the environment.
- Display the radar system and other known emitters on a heat map.
- Identify possible conflicts and make recommendations to the user, such as utilizing frequency de-confliction in the planning phase and/or EM Interference (EMI) mitigation opportunities in the operational phase.
- Work standalone as a planning tool or used in conjunction with a radar system to automate changes to the operating parameters of the radar system to support dynamic spectrum sharing and de-confliction efforts in real-time/near real-time.
Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. Owned and Operated with no Foreign Influence as defined by DOD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence Security Agency (DCSA), formerly the Defense Security Service (DSS). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this contract as set forth by DSS and MCSC in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advance phases of this contract.
PHASE I: Develop concepts and determine feasibility for planning aids, sensing equipment, software algorithms, or other methods to assist radar operators and spectrum planners. International Telecommunications Union provides recommendations ITU P.528 A Propagation Prediction Method for Aeronautical Mobile and Radionavigation Services using the VHF, UHF and SHF bands and ITU P.452 Prediction Procedure for the Evaluation of Interference Between Stations on the Surface of the Earth at Frequencies Above About 0.1 GHz provide a baseline for developing the models. Demonstrate the feasibility of military radars and commercial telecommunications systems co-existing in the same spectrum space. Establish that the concepts can be developed into a useful product for the Marine Corps. Material testing and/or analytical modeling, as appropriate will establish feasibility. Provide a Phase II development plan with performance goals and key technical milestones that addresses technical risk reduction.
PHASE II: Develop a full-scale prototype for evaluation. Evaluate the prototype through bench or lab testing to determine its capability in meeting the performance goals defined in the Phase II development plan and the Marine Corps requirements for S-Band spectrum sensing and de-confliction. System performance shall be demonstrated through prototype evaluation and modeling or analytical methods. Conduct system testing in a relevant environment. Evaluate and compare the results to the defined requirements. Prepare a Phase III development plan to transition the technology for Marine Corps use.
It is probable that the work under this effort will be classified under Phase II (see Description section for details).
PHASE III DUAL USE APPLICATIONS: Clearly identify and describe the expected transition of the product/process/service within the Government. Possible dual use applications include, civilian air traffic control applications or weather radars.
