Imaging Spectrometers/Radiometers
IRMSS
[Source: "The IRMSS for CBERS", Wang Huaiyi, Ma Wenpo, Beijing Institute of Space Machine and Electricity, Beijing] The IRMSS is a cross-track scanning imaging radiometer mainly operating in the infrared. It has one Panchromatic (Pan) band, two short-wave infrared (SWIR) bands and one long-wave infrared (LWIR) band. The spatial resolution of the Pan and SWIR bands is 78m in an orbit altitude of 778km while the LWIR band is 156m. Its swath is 120km, and the global coverage period is 26 days, Its key design characteristics are summarized in Table 1. The IRMSS mainly include a scanner mainframe, an amplifier assembly, and encoder, a power supply assembly, a command & telemetry assembly, a radiative cooler controller and a thermal controller. The scanner mainframe is composed of the mainframe structure, the linear scan mirror assembly, the scanning angle monitor, the telescope, the scan line corrector, the onboard calibration system, the relay optics, the focal plane assemblies, the pre-amplifiers and the radiative cooler.
