Ground-based microwave radiometer with high precision double channels

A new ground-based high precision double-channel microwave radiometer MWR-120-PCFE for atmospheric remote sensing is designed. The microwave radiometer adopts Peltier cooling front-end technology to increase stability, reduce the system noise, improve the sensitivity and signal quality. The dual-channel design provides the simultaneous measurement of microwave radiation at 110/115 GHz of two molecules, which improves the measurement efficiency. The use parabolic quasioptic system, integrated IF module makes the radiometer more compact and portable, reducing cost and complexity. The innovation and improvement of this microwave radiometer in technology makes it have a wider application prospect in the fields of atmosphere physics, meteorology, remote sensing, and provides greater convenience and efficiency for scientific research and practical applications.
