Research on Laser Jamming Model of Infrared Imaging System

With the application of laser jamming technology in the field of infrared imaging guidance weapons, the research on laser jamming performance and anti-jamming technology are paid more and more attention, and they are related to laser jamming model research closely. In order to construct a high confidence laser jamming model. Firstly, we analyzed the physical model of the laser jamming and the characteristics of full link transmission, and established a theoretical model of laser jamming. At the same time, we analyzed the influence law of different wavelength lasers in atmospheric transmission and the variation law of irradiance of different divergence angles with distance. Finally, by comparing the results of laser irradiation infrared camera experiment and digital simulation, we verified the coherence between the laser jamming model and the laser jamming image generated by experiment.
