Prediction of cryogenic temperature impact on the performance of space-borne IR sensors

Abstract: The sensitivity of a sensor system and its optical aperture size are two key parameters commonly used to characterize the performance of a remote sensing or space-borne surveillance system. In this work, a sensitivity model for space-borne staring IR sensor systems which are mainly used for point-source detection and identification is developed. Different noise components, including the photon noise from background radiation and near-field thermal radiation of optics, the electronic noise of sensors, as well a… Show more
