An infrared radiant augmentation technique for target drones

In order to test the performance of IR guidance weapon systems in the outfield experiment,it is necessary to load an IR augmentation device on target drone to simulate the IR characteristics of a real target plane.The commonly used IR augmentation has low IR radiation intensity and can not reflect the direction dependent radiation properties.An IR augmentation technique based on optic method is introduced.A high brightness IR light source is used to generate IR radiation.The radiation intensity is controlled according to the missile target-plane distance and direction,which are detected by an optoelectric tracing system.Based on the simulation results of the radiation intensities with different distances and radiation angles,an optical system is designed.The experimental results indicate that the IR radiation characteristics of a target with a maximal radiation intensity of 1600W/sr is simulated by using the technique.
