Airborne IRST system works in a wide temperature range,low pressure and small exposure size.The influence of detector parameters on detection performance is analyzed.The idea of reducing the refrigeration temperature of detector assembly to improve detection performance is put forward.Design and development of thermal control system for detector module based on airborne environment.After testing,the cut-off wavelength,detection rate and bad pixel rate of detector module have been improved.System equivalent detection capability increased by 15 %.The design idea has certain reference significance for improving the performance of infrared system.
