Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.
OBJECTIVE: Develop and demonstrate innovative receive-side sensitivity enhancements that improve signal acquisition, noise suppression, and interference mitigation for Multifunctional Information Distribution System (MIDS) terminals. This effort focuses on maximizing receiver performance independent of transmission power, leveraging advanced adaptive filtering, diversity techniques, and low-noise reception strategies to ensure reliable communication in contested and degraded environments. Solutions must be Field Programmable Gate Array (FPGA)-compatible, maintain low latency (=10µs), and integrate seamlessly into existing MIDS systems without degrading performance.
DESCRIPTION: The MIDS Program Office (MPO) is responsible for advancing tactical data link (TDL) communications, including Link-16 and Tactical Targeting Network Technology (TTNT). As modern battlefields become increasingly congested with electromagnetic interference, adversarial jamming, and spectrum competition, the ability to maintain a high-sensitivity, interference-resistant reception is critical to mission success.
This effort focuses on achieving significant sensitivity gains, enhancing the receiving capability of MIDS terminals by separating and improving the receive-side performance independent of transmitter-based enhancements. Current limitations in receiver sensitivity restrict the ability to capture and process weak signals, particularly in contested environments where interference mitigation and adaptability are crucial.
To address this, the Navy is seeking innovative solutions that integrate:
These enhancements will fundamentally improve the resilience and efficiency of MIDS terminals, enabling more robust signal acquisition and improved signal-to-noise ratio (SNR) under degraded conditions. Unlike traditional solutions that focus on boosting transmission power, this effort is uniquely centered on maximizing the effectiveness of the receiver itself, ensuring clear, uninterrupted reception even in challenging operational environments.
The Navy seeks mature solutions (Technology Readiness Level (TRL) 5 or higher) that can be implemented in FPGA architectures, allowing for real-time adaptation and rapid deployment. Proposed solutions should be capable of:
Of particular interest are adaptive diversity techniques, such as maximal ratio combining (MRC), spatial diversity, and multi-path fading mitigation, which can independently improve receive performance in highly dynamic environments. These innovations will provide a separate and robust receive-side enhancement, ensuring a more resilient and high-sensitivity reception capability for tactical data links.
The successful transition of these technologies will provide independent, receiver-focused improvements that support long-range, interference-resistant communication. This SBIR topic seeks vendors who have already demonstrated initial feasibility and validation of sensitivity enhancement techniques, with the goal of integrating these advancements into the MIDS terminal for operational deployment.
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 32 U.S.C. § 2004.20 et seq., National Industrial Security Program Executive Agent and Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA) formerly Defense Security Service (DSS). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances. This will allow contractor personnel to perform on advanced phases of this project as set forth by DCSA and NAVWAR 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 during the advanced phases of this contract IAW the National Industrial Security Program Operating Manual (NISPOM), which can be found at Title 32, Part 2004.20 of the Code of Federal Regulations.
PHASE I: Feasibility documentation MUST NOT be solely based on work performed under prior or ongoing federally funded SBIR/STTR work. Demonstrating proof of feasibility is a requirement for a Direct to Phase II award.
For this Direct to Phase II topic, the Government expects that the small business would have accomplished the following in a Phase I-type effort:
FEASIBILITY DOCUMENTATION: Offerors interested in proposing to this Direct to Phase II topic must include in their response Phase I feasibility documentation that substantiates the scientific and technical merit; proof that Phase I feasibility (described in Phase I above) has been met (i.e., the small business must have performed Phase I-type research and development related to the topic, but feasibility documentation must not be solely based on work performed under prior or ongoing federally funded SBIR/STTR work.); and describe the potential commercialization applications. The documentation provided must validate that the proposer has completed Phase I-type development of technology as stated above. Documentation should include all relevant information including, but not limited to: technical reports, test data, prototype designs/models, and performance goals/results. Work submitted within the feasibility documentation must have been substantially performed by the offeror and/or the principal investigator (PI).
PHASE II: The contract type for topic N252-D11 will be Cost-Plus-Fixed-Fee.
The selected small business will design, develop, and prototype receive-side sensitivity enhancements aimed at improving the signal acquisition and interference mitigation capabilities of MIDS terminals. The primary focus is to implement and validate high-sensitivity reception techniques that operate independently of transmitter-based improvements, ensuring more reliable communications in contested and degraded operational environments:
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: Transition the developed technology for Navy deployment:
Advanced interference mitigation techniques have applications beyond military systems, including:
