Description

The National Oceanic and Atmospheric Administration (NOAA), National Polar-Orbiting Operational Environmental Satellite System (NPOESS), Integrated Program Office (IPO), proposes to enter into a contract with the Ohio State University Research Foundation (Columbus). The authority for execution of this proposed contract by NOAA is 41 U.S.C. 253(c)(1), "only one responsible source and no other supplies or services will satisfy agency requirements". The term of the contract will be for 12 months, with one 12-month option for extension to the term of performance. During the initial year of performance, and expanding in the second year, Ohio State University will develop and demonstrate advanced technologies for interference mitigation in passive microwave sensors operating at C-band. In particular, a digital receiver-based microwave radiometer including an interference mitigation processor will be deployed in C-band brightness measurements from an aircraft platform. The digital receiver will be capable of capturing 100 MHz of bandwidth at near 100% duty cycle through use of analog to digital converters (ADCs) operating at 200 mega samples per second (MSPS). High dynamic range (10 bit) ADCs will be utilized and are essential to this study; the resulting receiver will be capable of mitigating interference in real time through both temporal and spectral suppression operations. Interference mitigation algorithms will be developed in Altera Hardware Design Language (AHDL) and implemented in Altera Stratix Field Programmable Gate Array (FPGA) components. Data will be collected to quantify the ability of the interference mitigation processor to remove temporally and/or spectrally localized radio frequency interference contributions to observed brightnesses. These studies will be instrumental to designing and assessing modifications to the NPOESS CMIS sensor to improve performance in the presence of radio frequency interference. The Ohio State University team has previously developed digital receiver technologies for radio frequency interference mitigation in microwave radiometry; the proposed project is based upon designs developed by this team. The expertise of this team has resulted in a digital receiver designs capable of capturing 100 MHz of bandwidth at near 100% duty cycle, and of mitigating interference in real time. The designs available are based on 200 MSPS, 10 bit ADCs, and intended for use in Altera Stratix FPGA components. The proposed co-Principal Investigators (co-PIs) have led a NASA sponsored Instrument Incubator Program to develop these technologies; the unique knowledge required to perform the studies of the proposed project is available only from this team. The Ohio State University team also has expertise in the design and implementation of interference mitigation algorithms. The proposed project will require continuous assessment and revision to the mitigation algorithms implemented in the processor, to ensure that maximum effectiveness is achieved. Past experience with real-time analysis and mitigation of radio frequency interference for microwave radiometry is essential for this project, and is available only from the proposed team. The system designs previously developed, the implementation expertise, and the experience in development and application of interference mitigation algorithms give the Ohio State University team the extent of unique expertise to perform this sole source requirement. The singular expertise and resources of the Ohio State team cannot be secured from other public or private institutions. Any other party desiring consideration for this requirement must identify its full capability in writing to the Contracting Officer within 45 days of this publication. No RFP or solicitation is available. No further CBD notice is planned. See Notes 22, 25, and 26.
