Abstract

See full text

An omnidirectional measurement system for a time-varying characteristic of atmospheric vapor radiation includes an antenna and calibrator assembly, a receiver assembly, a room temperature IF assembly, and a data acquisition and system control assembly. Atmospheric vapor features a wide profile and strong radiation in a frequency band of 183 GHz, and is often seen in the characteristic measurement of atmospheric vapor in high-altitude areas. The omnidirectional measurement system combines a superconductor-insulator-superconductor (SIS) mixer with high detection sensitivity in the frequency band of 183 GHz with a structure that integrates pitch scanning, omnidirectional scanning, and automatic calibration to achieve fast and high-precision omnidirectional scanning measurement of the time-varying characteristic of atmospheric vapor radiation. The omnidirectional measurement system has a pitch adjustment-based fast omnidirectional scanning function, and can measure the time-varying characteristic of atmospheric vapor radiation with higher precision and higher temporal resolution through the SIS mixer with higher sensitivity.
