Expected Technology Readiness Level (TRL) upon completion of contract: 6

TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This Phase II proposal, builds upon the extensive research and digital radar design that has been successfully completed during the Phase I contract. Key innovations of the proposed Phase II work will be

• High update rate software configurable Direct Digital Synthesizer (DDS) design. The state-of-the-art DDS ICs can operate at 1 GHz update rates. IAI proposes to achieve the same or higher update rates, with increased flexibility (in frequency/ phase tuning) which arises from the software defined nature of the DDS implementation.

• High-sampling rate (400 MHz and above), multi-channel digital receiver design. On-board signal processing capabilities will be integrated in the receiver. This includes digital implementation of commonly used radar receiver architectures (Digital down-up conversion, Digital filtering, Correlation, SAR imaging).

• Digital implementation of direct RF generation techniques for L-Band frequencies. Flexible and scalable analog up-conversion techniques would be implemented to generate frequencies in the S-Band, X-Band, going up to the Ku band.

• Scalable and modular hardware architecture to support multiple radar missions. Such a design approach would also address the issue of portability between different reconfigurable logic device families/ vendors.

• Technology transition to adapt the radar design to meet space qualified standards.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed technology is built upon the radar design and communications expertise of IAI, developed over several SBIR and non-SBIR contracts. Our innovation is the digital synthesis of critical radar blocks and reconfigurable design to support most commonly used radar modes.
Our proposed technique can be used for a wide range of remote sensing applications for NASA including:

• High bandwidth channel sounders
• Weather surveillance radar for aircrafts
• Earth science measurements like surface deformation, topography and soil moisture measurements
• Space based radar missions
• Non-cooperative target tracking radar in air space

IAI has a long history of successfully designing custom radars for DoD and NASA, and most NASA applications could be supported by our reconfigurable radar design.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The most promising Non- NASA commercial applications are:

• Reconfigurable radar for commercial applications
• Cognitive Radios/ Radar for Defense related applications
• High bandwidth arbitrary waveform generator
• UAV based applications (due to the small form factor and plow power). This would include UAV based weather surveillance, target tracking and other commonly sought after UAV radar applications

IAI has tremendous experience of designing customized radar assembly and packaging them as field-ready units.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
