Problems solved by technology

[0004] Conventional infrared simulation methods usually only focus on the simulation of the target, and the weather conditions need to be manually set according to the simulation scene, and less consideration is given to dynamic conditions such as the target's movement relative to the sensor, making it difficult to cover the complex sky background in the simulation of small targets in the air , meteorological conditions, and dynamic flight scenarios limit the degree of automation and simulation accuracy of the simulation method
