Light Capacitance Type Refractometer to Measure Atmosphere Parameter
The precise measure of atmospheric refractive index is one of the key factors which leads a guarantee of accurate estimate in the atmospheric refraction error margin and the forecast of atmosphere wave in the electronics systems, such as radar and correspondence—etc The error of 59 radiosonde which are in common used to measure atmospheric refractive refraction index is bigger, the microwave refract meter which has high accuracy also has the characteristics of high expenses, big weight of the instrument, those all bring very big restriction to engineering physically applications. For this cause, according to the principle that the variety of atmospheric refractive index brings frequency to the LC shock loop which composed by fixed inductance and air capacitor, this paper designs a light capacitance type refract meter which is use low temperature degree coefficient air capacitor for measure of sensitive component. Experiment validated: The precision of light capacitance type refract meter is more better than 59 radiosonde in measuring atmospheric refractive index, and it has no spacetime measure error when sending out the temperature, wet, pressure respectively which is common find in 59 radiosonde, and it has advantages like light weight, small lag coefficient etc..
