A retractable infrared and laser fusion target

This paper presents a retractable infrared laser characteristic fusion target design configuration. In this configuration, the folding mechanism provides the retraction and playback function to drive the simulated target to extend in the length direction, and the extension length can be adjusted according to the background and scene requirements. The simulated target has both infrared and laser characteristics, which can provide a fixed laser reflectivity and cross-sectional area of the characteristic body target. At the same time, the characteristic body target has infrared radiation characteristics of 3~5um and 8~12um bands, respectively, for detection and recognition of high-sensitivity infrared detector, and for the verification of laser range finder's ranging ability.
