Monitoring system of changes in air composition
Journal: Monitoring systems of environment
Year: 2021

The article considers a new approach to air monitoring based on phase-measurement in the SHF range and homodyne frequency conversion. Information about the change in the air composition is obtained by determining the phase progression of the microwave signal when it passes through the environment under study. At the same time, to determine the change in the content of exclusively harmful gases in the air composition, the meteorological component of the environment is subtracted from the informat
