Graduate students working together on the Ku-band solid-state radar transceiver optimization testbed.

Mr. Mansur Tyler, an American Indian student, is working on solid-state radar scattering experiment and usage of the information for better transceiver design in a brand new facility at OU.

This project completes the first comprehensive studies and applications of Adaptive Pulse Compression (APC) and joint transceiver optimization implementations with airborne weather radar, which is an emerging and unique research area in the state of Oklahoma. It solves the range sidelobe contamination problem by innovative algorithms and software and proves the feasibility of applying the algorithms to actual NASA radar data. The OU team is currently working with NASAGSFC team to deploy the technologies to current NASA-operating radar and data products. The technology is also successfully applied to OU’s ground based solid-state radar in 2013-2014, and obtained significantly improved sensing result for the May 2013 Moore, OK tornado observation campaign. The technologies developed in this project are used in other ongoing projects developments beyond weather remote sensing applications. An important application developed during the period

is the improvements in general air-surveillance, especially for the detection, tracking and identification of small aerial objects including small unmanned aerial vehicles (UAVs), which is a new research area emphasized by state of Oklahoma. Technology was successfully applied to GBSAA and ABSAA experiments and achieved significant impacts on the DoD organized UAS-EXCOM in 2014. The EPSCoR project supported the design and build of the first large scale fixed wing unmanned aerial vehicle – OUAV-One in OU campus, in 2013, which laid a potential infrastructure for future flight test of our new radars for atmospheric remote sensing research. Collaboration with Garmin International from 2013 is a milestone of the program which not only allowed the research and development team in state of Oklahoma to transfer the technology to commercial products, but also allowed them to learn from an industrial leader in airborne radar area.
