Abstract

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.
