Abstract

The interference factors produced by the strong radiation interference source in the infrared imaging system are mainly: super-saturation crosstalk effect, spatial transfer characteristic ambiguity phenomenon, halo effect and transient environmental temperature adaptability. These interference phenomena will reduce the imaging of the infrared imaging system, produce instantaneous “blinding” or key information loss, and affect the advantages of the system in target detection, capture, identification and tracking. The formation mechanism and theoretical basis of each influencing factor are analyzed, and the methods of eliminating interference characteristics are studied. Through experimental research, the method of judging the imaging quality of the infrared imaging system at different temperatures is studied. The results show that the temperature adaptability of the infrared imaging system greatly affects the performance of the system detection and recognition. Therefore, the research on the temperature adaptability of the infrared imaging system can provide a basis for the quantitative characterization and simulation calculation of the interference characteristics of strong radiation sources in order to increase the application of the system in the research field and propose ideas for further research.
