Abstract
This study will provide the basis to advance microwave radiometer calibration technology using internal active devices. CME proposes the design of a small, automated, stepped cold/warm noise source injection calibration device to simplify on-board calibration. We will build upon existing FET cold noise technology and develop an innovative calibration concept applicable to spaceborne, airborne, and ground-based radiometers. For direct access to leading edge foundries, we propose to investigate and characterize emerging Raytheon FET technologies and develop innovative methods of improving radiometer calibration. This effort leverages CME's microwave radiometer R&D experience on our Air Force Phase II SBIR contract for a small ground-based, multi-frequency microwave radiometer. Teamed with Raytheon's Microwave Remote Sensing Group and Dr. L.P. Dunleavy from University of South Florida's Wireless and Microwave research program, CME can effectively address NASA's need for new calibration technologies. Phase I will result in a device design for a new microwave radiometer calibration system capable of replacing on-board, complex and expensive state-of-practice techniques. This effort will provide a solid foundation leading to a proven automated calibration device for smaller on-board microwave radiometers in future spacecraft sensors.
