Paper Abstract

The space-borne HgCdTe infrared detector is widely used in missile warning and interception because of its ability to detect the active tail flame of the missile. The performance of the infrared detector on satellite directly affects the missile's identification and threat assessment. In order to study the effect of temperature on the performance of satellite infrared detector, Noise-Equivalent Temperature Difference(NETD) of the HgCdTe detector is used as the performance reference, and the SBIRS near-earth orbit small satellite's cosmic environment is the analysis background. Radiant energy of the target is analyzed with distance changes. The performance of HgCdTe detector with temperature and distance changes was simulated by mathematics software MATLAB. Which is been used to simulate the change of Noise-Equivalent Temperature Difference due to the increased operating temperature and distance change of HgCdTe infrared detector. which provided calculations reference for the performance analysis of HgCdTe detectors on the satellite.
