Description

ABSTRACT: This Phase I SBIR proposal describes our plan to develop a compact dual-channel V-band and W-band radiometer for measuring total path attenuation on a satellite to ground communications link. Design goals for this instrument include a compact design with built in calibration loads, including a COLFET that achieves a low temperature reference without the need of cryogenic cooling. To simplify the electronics design, direct detection at RF is anticipated. Phase I research will result in a detailed radiometer design, and an algorithm coded to extracting total path attenuation from measured brightness temperature. BENEFIT: Successful development of the proposed dual band radiometer will result in a compact, all-weather instrument suitable for continuous monitoring of total path attenuation. Attention to a modular design adaptable to other frequency bands, in a compact package suitable for installation in standard aircraft probe canisters will promote sales for ground-based as well as airborne applications.
