technology within this topic is restricted under the International Traffic in
Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and
import of defense-related material and services, including export of sensitive
technical data, or the Export Administration Regulation (EAR), 15 CFR Parts
730-774, which controls dual use items. 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 section 3.5 of 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.
Develop an open architecture, portable, podable, relatively low size, weight,
and power (SWaP) reprogrammable solution to focus computing power on high-speed
streaming data in order to rapidly extract and identify signals of interest.
Electronic receiver bandwidth and fidelity capabilities are increasing rapidly.
Each of these attributes increases file size of stored radio frequency (RF)
sample data and data rates streaming to those sensors. In most cases, the data
is packaged into summary descriptor format (such as pulse descriptor words
(PDWs)) for further ingest by on-board computing resources or stored for off-board
processing. Turning the In-Phase Quadrature (IQ) data into PDWs leaves the
potential for unprocessed and unexploited data of which the end user is
unaware. Reference 3 explains the current method of forming PDWs and the type
of information they contain. There is no common standard for PDWs as each
vendor uses their own signal detection, classification, and PDW generator
algorithm. Select a PDW format that best suits the development of the approach
to signal identification.
A method for collecting and exploiting the unprocessed and unexploited data
that needs to be developed. Develop a capability whereby an operator can
selectively filter unexploited data real-time in frequency, time, or other
method. The ability to look for correlation with existing emitter files and/or
to identify emitters of interest in an electromagnetic (EM)-dense environment
frequency band at the point of actual IQ data, before the PDW summary
information is formed which can potentially result in loss of information is
For this SBIR topic, the term “emitters of interest” can be communication
signals in a population-dense urban environment, such as individual cell
phones, radio, television, or satellite communication. The general idea of this
system is the ability to detect a specific signal, like a military type
emitter, in an EM-cluttered urban environment—taking into account that the
emitter of interest will be using benign signals to hide its intent or actions.
The system must take advantage of the many Open Systems Architectures (OSAs)
that are available so that as threat systems advance, the system can be
reprogrammable with new algorithm improvements to respond to ever changing
threats. Examples include OSAs such as Open System Architecture (OSA), Sensor
Open System Architecture (SOSA), and/or Modular Open System Architecture
The resulting system should be able to analyze 1GHz - 4GHz of instantaneous
bandwidth and cover as much frequency as possible, 0.1 – 18 GHz preferred, more
The final design should be compatible with standard Air Transport Radio (ATR)
chassis or equivalent chassis with SWaP requirements of fitting in a 7-10 inch
diameter pod such as the ALQ-167, convert 400Hz to 28V DC, and use 350 Watts or
less power. Operational system will have access to 3 PHASE 400 Hz 115/200VAC at
10A per PHASE.
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 Security Service (DSS). The
selected contractor and/or subcontractor 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 DSS and NAVAIR 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 advanced phases of this
I: Propose a new Electronic Warfare receiver architecture where such a
system could reside, how it could access data, how it could be steered or
reprogrammed, and what the capabilities of rapidly inferring RF environment
from raw data samples are (e.g., latency, fidelity). The proposed should
understand that there is a high probability of there being multiple signals
within the frequency range of interest. Feedback from the PDW formation process
is an option to aid in deinterleaving, but the proposed approach should rely on
the predetermined mission data files that specify emitter parameters as a final
option. System must have a way of dealing with the possibility that an
emitter-mission data file is not loaded and providing the user with an
acceptable solution. The Phase I effort will include prototype plans to be
developed under Phase II.
II: Prototype a solution with (for example) GUI interaction for reprogramming
of a high bandwidth data stream. Simulate the data stream or provide by other
efforts - such that Phase II does not become an activity of designing a
high-speed receiver. The prototype should instead focus on aiding
interpretation of the data.
Work in Phase II may become classified. Please see note in Description
III DUAL USE APPLICATIONS: Perform final testing with a real-world EM dense
environment to test the developed algorithms. Demonstrate the ability to
identify complex emitters. Transition and integrate into appropriate platforms
and systems. Successful technology development would benefit Commercial Airport
Monitoring, as well as Frequency monitoring for the communication industry.

** TOPIC NOTICE **
These Navy Topics are part of the overall DoD 2019.3 SBIR BAA. The DoD issued its 2019.3 BAA SBIR pre-release on August 23, 2019, which opens to receive proposals on September 24, 2019, and closes October 23, 2019 at 8:00 PM ET.
Direct Contact with Topic Authors. From August 23 to September 23, 2019 this BAA is issued for Pre-Release with the names of the topic authors and their phone numbers and e-mail addresses. During the pre- release period, proposing firms have an opportunity to contact topic authors by telephone or e-mail to ask technical questions about specific BAA topics. Questions should be limited to specific information related to improving the understanding of a particular topic’s 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 (SBIR/STTR Interactive Topic Information System). After this period questions must be asked through SITIS as described below.
SITIS Q&A System. Once DoD begins accepting proposals on September 24, 2019 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. However, proposers may submit written questions through SITIS at https://sbir.defensebusiness.org/topics . In SITIS, the questioner and respondent remain anonymous and all questions and answers are posted electronically for general viewing.
Topics Search Engine: Visit the DoD Topic Search Tool at sbir.defensebusiness.org/topics/ to find topics by keyword across all DoD Components participating in this BAA.
Help: If you have general questions about DoD SBIR program, please contact the DoD SBIR Help Desk at 800-348-0787 or via email at firstname.lastname@example.org
