Comparative Assessment of Radio Noise Signal Losses in Radio Frequency and Radiophoton Microwave Transmission Line

This paper presents the results of experimental studies of variants of construction of intermediate frequency paths of microwave radiometric systems, based on the traditional scheme of construction with the use of copper coaxial lines of transmission of intermediate frequency signals of microwave radiometric receivers and perspective radio photonic fiber-optic line of transmission of microwave signals with internal modulation. The aim of the work is to evaluate the possibility of realization of the radio-photon tract for transmitting signals of intermediate frequency as a part of promising microwave radiometric systems for remote sensing of the atmosphere. The objectives of the work are to analyze the performance of the radio photon transmitters and receivers of Microwave Photonic Systems, Inc. as a part of the intermediate frequency path of the multi-frequency microwave radiometric system of remote sensing of the atmosphere, compared to the coaxial radiofrequency transmission line.
