| 摘 要： | 介绍了高光谱分辨率光谱定标经常采用的几种技术手段，包括谱线灯法、单色准直光法、利用可调谐激光器和气体吸收池的方法等。通过对比几种国外高光谱分辨率大气痕量气体探测仪的光谱定标技术，阐述了不同光谱定标技术的原理、实施方法以及技术特点。针对大气痕量气体探测遥感器超高分辨率光谱定标的特点，指出定标设备的带宽应能达到0．001nm的水平，同时还应考虑采取优化定标算法、结合多种光谱定标方法等措施来满足高光谱分辨率大气痕量气体探测仪光谱定标的要求。

| Abstract: | Several kinds of spectral calibration technologies are introduced in detail, including the spectrum lamp spectral calibration, mono-chromator spectral calibration, tunable laser spectral calibration, and the gas cell spectral calibration. The experimental principle, experimental methods and technical characteristics of dif- ferent spectral calibration technologies are described by analyzing and comparing foreign high spectral remote sensors for trace gases. Based on the characteristics of ultra-high resolution spectral calibration for atmospheric remote sensors, it points out that the bandwidth of calibration equipment should reach the level of 0. 001 nm. It also suggests that the calibration method of improving optimization algorithm and comprehensive calibration methods should be considered to ensure the high spectral calibration accuracy of high spectral remote detectors for trace gases. |
