TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Intelligent Automation, Inc (IAI) and its university partner, University of Oklahoma (OU), Norman, propose a forward-looking airborne environment sensor based on active weather radar technologies. The sensor consists of a software-defined radar transceiver, compact dual-polarized array antenna operating in the X-band as well as an integrated RF analog front-end. By leveraging dual-polarization processing, the system will be able to extract atmospheric parameters; thus it will be able to identify and classify the atmospheric conditions as well as local obscurants. The software defined radar transceiver has a Direct Digital Synthesis (DDS) component which can easily generate high bandwidth chirp waveforms (bandwidth >=200 MHz) and pulse shaping can be defined digitally to reduce the side-lobes considerably.

IAI is currently developing a software defined radar (SDR) platform that can adaptively switch between different modes of operation for radar, by modifying both transmit waveforms and receive signal-processing tasks on the fly. The proposed multi-channel radar technique and the system design will leverage IAI's vast experience in SDR, RF hardware design and antenna design and OU's capabilities in microwave design and field-proven atmospheric hazard modeling and detection algorithm development.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed technology is built upon the radar design and communications expertise of IAI and our sub-contractors at OU. The most promising commercial applications of interest to NASA are:

• Weather surveillance
• Earth science measurements
• Reconfigurable radar

IAI has a long history of successfully designing custom radars for 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:

• Arbitrary wideband waveform synthesizer
• Reconfigurable radar transceiver with multi-mode capabilities
• Commercial aircraft collision avoidance and safety
• High speed digital waveform reader
• UAV based applications (due to the small form factor and low 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. Again, if technically the project is successful, we will approach large, established companies in this market segment with the goal of licensing our technology and possible collaboration for Phase II efforts.

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.
