ACQUISITION PROGRAM: JSF - Joint Strike Fighter Program

The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services. Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 3.5.b.(7) of the solicitation.

OBJECTIVE: Develop innovative pulse interleaving techniques to facilitate the multiple simultaneous mode operation in Naval radar systems in order to improve situational awareness in a littoral environment.

DESCRIPTION: Traditional radar mode interleaving is done by dedicating specific time periods for each mode. However, with the increasing proliferation of very capable Naval radar systems [including those utilizing active electronically steered arrays (AESA)], there is potential for performance gains to be realized by implementing mode interleaving at the radar pulse level. Investigate pulse interleaving of two or more radar modes with differing temporal baselines. Focus on air-to-surface modes (moving target indicator search, tracking and imaging) where ocean and surface craft scattering phenomenology also must be considered. In addition, investigate the pulse interleaving of air-to-air and air-to-surface modes.

PHASE I: Determine the feasibility and potential performance benefits of advanced radar techniques that use pulse interleaving of two or more modes with differing temporal baselines.

PHASE II: Develop specific parameter sets for advanced radar modes that utilize pulse interleaving. Develop the parameter sets to allow demonstration on either an existing, fielded or experimental AESA radar and quantify the expected performance benefits.

PHASE III: Demonstrate the parameter sets on either an existing fielded or experimental AESA radar to validate the predicted performance benefits and provide the basis for technology transition to one or more Navy airborne radar systems.

PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: The techniques developed under this SBIR could find application in a number of finds application in a wide range of civilian communication systems. The general models developed under this SBIR could be modified to support these civilian applications.
