“In the field of space-based Earth observation and astronomical detection, the research progress in mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) detection technology is significant. Experts have conducted a comprehensive analysis of key performance indicators for IR detection systems, including ground sampling distance (GSD), operation range, and noise equivalent temperature difference (NETD), and their interconnections with IR detector parameters. This research provides solutions to address the unique demands of diverse space-based IR detection scenarios and lays a foundation for the construction of high-quality space-based observation platforms.”
