Research on the detection performance of infrared photoelectric tracking system for high-speed projectile

In order to evaluate the detection performance of the infrared photoelectric tracking system for high-speed projectile and establish a stable target tracking platform, the projectile radiation characteristics of the detection area of the infrared photoelectric tracking system based on the imaging detection principle is studied, the projectile reflection radiation model and the projectile infrared radiation model are established, and the calculation function of the projectile total radiation intensity is given. Combining the inherent parameters of the system, the calculation model of detection distance of the system is constructed, and the detection performance of the system is analyzed. Based on the design parameters of the infrared photoelectric tracking system, the variation rules of radiation energy obtained from the sensitive surface of the infrared imaging sensor under the sky background brightness, different flying attitudes of the projectile and different detection distances are calculated and analyzed; the correctness and scientificity of the detection distance model of the infrared photoelectric tracking system is verified by collecting the information of the system output target signal under different test conditions
