OBJECTIVE: Develop a low-cost, covert, high-speed, high-density means of transmitting and receiving broadband data for use on Navy Land/Sea/Air platforms.

DESCRIPTION: The U.S. Navy requires a high-capacity, covert communication link providing two-way communication through free space. This communication link must be covert, or undetectable, which has a low probability of intercept (LPI) or a low probability of detection (LPD) and cannot be susceptible to jamming. The communication path must allow for fast, large-data transfer(s) from one aircraft to another aircraft and/or sea- or land-based hub. The types of data include, but are not limited to, the following types of data: maritime tactical information, imagery (Still and Full Motion Video), Synthetic Aperture Radar, Multi-and hyper-spectral imagers, Precise Navigation and Timing (PNT) data, Electronic Warfare, and Acoustic data.

The goal of this SBIR topic is to develop a covert, wideband communication device that supports a 100 Mbps data transfer rate at line of sight ranges (150 nm). The first challenge for many engineers in wireless communication design is how to overcome white Gaussian noise. The proliferation of wireless technologies has also added hostile noises as a major cause of interference. A covert, high-bandwidth communication device could overcome a harsh Gaussian environment even with the addition of hostile noises while maintaining a high-bandwidth data transfer. If Radio Frequency (RF) is used as the transmission source, desired bands are L band to X band, Ku band, and Ka band ability with the ability to transmit and receive (TR/RX) in multiple bands. The volume of the device should be less than 4.5 ft3 (0.127 m≥). The weight should be less than 50 pounds (22.7 kg). The estimated cost per unit should be less than $50K per kit. Conformal antennas are desired to limit the drag impacts on the host aircraft. The system is required to be undetectable outside of the main beam (i.e., highly directional, meaning you have to be in the path to intercept). For RF, the system should be able to null noise sources, in addition to being a non-detectible signal below the RF noise floor and agile enough to mitigate against jamming sources. The desire is to limit the number of moving parts to reduce the sustainment footprint of this device.

PHASE I: Develop, design, and demonstrate a strategy, taking into consideration the feasibility and suitability for a covert high-speed, high-capacity airborne communication link. Identify potential roadblocks likely to be encountered and possible roadblock solutions. Recommend an architecture and implementation plan. Illustrate the benefits of being able to pass high-speed, high-capacity data covertly. The Phase I effort will include prototype plans to be developed under Phase II.

PHASE II: Based on the architecture and algorithms, develop a working prototype to include high-level requirements, software development, testing, and demonstration.

PHASE III DUAL USE APPLICATIONS: Perform final testing, and finalize the prototype. Develop platform integration execution plans, and engineering documentation, suitable for the transition of a functional prototype.

Covert netted high-bandwidth communications, wireless sensors and multimedia communications are increasingly becoming a required asset for success in modern society. As a result, issues surrounding their effective use, safety, and security are becoming more important. Even for commercial applications, covert commercial communication platforms will help protect private and sensitive information by reducing the possibility of interception and compromise.

Additionally, wireless communications often suffer from hostile noises or hostile noise environments. This would have commercial use for anyone who uses wireless technologies.

The Navy Topic above is an "unofficial" copy from the overall DoD 21.2 SBIR BAA. Please see the official DoD Topic website at for any updates.

The DoD issued its 21.2 SBIR BAA pre-release on April 21, which opens to receive proposals on May 19, 2021, and closes June 17, 2021 (12:00pm edt).

Direct Contact with Topic Authors: During the pre-release period (April 21 thru May 18, 2021) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic. Once DoD begins accepting proposals on May 19, 2021 no further direct contact between proposers and topic authors is allowed unless the Topic Author is responding to a question submitted during the Pre-release period.

SITIS Q&A System: After the pre-release period, proposers may submit written questions through SITIS (SBIR/STTR Interactive Topic Information System) at, login and follow instructions. In SITIS, the questioner and respondent remain anonymous but all questions and answers are posted for general viewing.

Note: Questions should be limited to specific information related to improving the understanding of a particular topicís requirements. Proposing firms may not ask for advice or guidance on solution approach and you may not submit additional material to the topic author. If information provided during an exchange with the topic author is deemed necessary for proposal preparation, that information will be made available to all parties through SITIS. After the pre-release period, questions must be asked through the SITIS on-line system.

Topics Search Engine: Visit the DoD Topic Search Tool at to find topics by keyword across all DoD Components participating in this BAA.
