场地自动化观测辐射计的设计与实现
Design and Implement of Automated Site Observing Radiometer
摘要
为了解决场地替代定标中人工测量地表反射率的不足,提高定标频次,获取大量连续的观测数据,研制了场地自动化观测辐射计,该辐射计共8个通道,覆 盖可见及近红外波段,光谱带宽20~40 nm,通过北斗卫星实现远程数据传输,可以实现无人职守下的自动观测和数据回传。对该仪器的工作原理、各单 元的设计和特点进行了描述,并给出了辐射计的室内辐射定标方法和结果,最后介绍了辐射计在敦煌辐射校正场的实验情况。
Abstract
In order to solve the shortcoming of reflectance’s manual measurement in vicarious calibration, improve the calibration frequency and obtain substantial and continuous data, an automated sited observing radiometer was developed which has eight channels with bandwidth from 20 to 40 nm covering the spectral range from visible to near-infrared. Furthermore, the data transmission was realized through Beidou satellite. The radiometer can realize automatic observation and data transmission without man attending. The operating principle of the instrument, the design schema and the characteristics of each unit were presented in detail, following the method and result of laboratory radiation calibration. The experiment of radiometer on Dunhuang testsite was been introduced at last.
