【摘要】 对地观测任务“远红外出射辐射认知和监测（Far-infrared Outgoing Radiation Understanding and Monitoring, FORUM）”在2019年被选定为欧洲空间局（European Space Agency, ESA）“生命的行星计划”中“地球探测器”的第9个任务。FORUM任务的目标是测量大气平流层和对流层在100～1600 cm^-1（即6.25～100■m）范围内的远红外发射光谱，其红外有效载荷包括非成像的傅里叶变换光谱仪——FORUM探测仪（FORUM Sounding Instrument, FSI）和FORUM嵌入式成像仪（FORUM Embedded Imager, FEI）。在A/B1阶段方案研究期间，ESA分别投资了两个团队，开展了A、B两个方案研究。空客防务航天公司（Airbus Defence and Space GmHB, ADS）牵头A方案，泰雷兹阿莱尼空间英国有限公司（Thales Alenia Space Ltd-UK, TAS-UK）牵头B方案。本文重点介绍了TAS-UK的B方案中FSI和FEI两台红外有效载荷在B1阶段进行的设计及关键技术研究状况。更多还原

【Abstract】 In 2019,the FORUM（Far-infrared Outgoing Radiation Understanding and Monitoring） mission has been selected by the ESA as the ninth mission Earth Explorer in the Living Planet Programme. It will measure the emission spectrum of the Earth′s stratosphere and troposphere in the spectral range of 100 to 1600 cm^-1（i.e.6.25 ■ m to 100 ■ m）. The FORUM space segment consists of a single satellite carrying two optical instruments: the FORUM Sounding Instrument（FSI） and the FORUM Embedded Imager（FEI）. The primary optical instrument is an infrared-atmospheric-sounder Fourier transform spectrometer. During the FORUM phase A/B1, studies have been led by Airbus Defence and Space（UK） and Thales Alenia Space Ltd（UK） as mission prime contractors, with concept A and concept B respectively. This paper will describe the design and key technology research progress of concept B of the FSI and FEI.更多还原
