Abstract

The measuring accuracy of atmospheric refractivity directly affects the precision of radar refraction error correction and atmospheric duct measurement. Because the conventional gas sensor can not accurately measure the atmospheric refractivity, the sensor–high Q microwave resonator that can accurately measure the atmospheric refractivity on-line is proposed basing on the principle that resonant frequency will change as different medium pass through the microwave resonator. Many aspects of the microwave resonator, such as the size, electromagnetic coupling ventilation material and processing technology are designed to ensure the measuring accuracy of the sensor. The results of experiment show that the sensor has the advantages of higher measuring accuracy and faster measuring speed, and the measuring accuracy of atmospheric refractivity can meet the request of radar refraction error correction and the atmospheric duct measurement.
