With the acceleration of the localization of our military equipment, it is necessary to evaluate the application effect of domestic core electronic devices in order to promote the engineering application of domestic core electronic devices in our military equipment. Firstly, the background and necessity of the evaluation of the application effect of domestic infrared detectors are introduced, and the application effect evaluation methods of domestic infrared detectors at the device level, module level, equipment level and system level are described in detail. The application effect of the detector in the airborne system has been scientifically evaluated, which can lead to the optimization and improvement of the domestic infrared detector, so as to support the comprehensive guarantee and reliability design of our military equipment manufacturers.
