Abstract

The Michelson interferometer, IRIS-D, flown on Nimbus 4 in April 1970 is an improved version of the interferometer, IRIS-B, flown on Nimbus 3 a year earlier. Thermal emission spectra of the earth are being recorded between 400 cm(-1) and 1600 cm(-1) with a nominal spectral resolution of 2.8 cm(-1) and a noise equivalent radiance between approximately 0.5 and 1 erg sec(-1) cm(-2) ster(-1) cm. This paper describes the design and performance of the IRIS-D and concentrates on the design differences that exist between the interferometers flown on Nimbus 3 and 4. The performance is demonstrated by examples of spectra obtained while in earth orbit.

摘要

1970年4月搭载在“雨云4号”卫星上的迈克尔逊干涉仪IRIS - D，是一年前搭载在“雨云3号”卫星上的干涉仪IRIS - B的改进版本。目前正在记录地球在400厘米⁻¹至1600厘米⁻¹之间的热发射光谱，其标称光谱分辨率为2.8厘米⁻¹，噪声等效辐射率约在0.5至1尔格·秒⁻¹·厘米⁻²·球面度⁻¹·厘米之间。本文描述了IRIS - D的设计与性能，并着重介绍了搭载在“雨云3号”和“雨云4号”卫星上的干涉仪之间存在的设计差异。文中通过在地球轨道运行期间获取的光谱示例展示了其性能。
