The Sun Radiometer Front-End Data Acquisition Circuit Design and Reliability Analysis

Abstract

In order to achieve the optical remote sensing ground calibration and improve its field calibration's accuracy and effectiveness, this paper conduct the corresponding optimized design of its data acquisition module according to WMO related performances of solar irradiance meter. The corresponding optimized design includes selecting multi-type photoelectric sensors to ensure the effective collection of light in each band, selecting especial chips for the important components of the acquisition circuit to ensure its reliability in harsh working environments and taking shielding protection on the important signal in the circuit, etc. After experimental verification in laboratory, data acquisition module shows its good stability and linearity, so it could better assist optical remote sensing satellite ground calibration.
