模块化热图再现技术研究

Investigation on modular reappearing technology for infrared images

为解决红外示假技术中的可控性问题,提出了利用模块控温实现热图再现的技术途径。通过类比LED显示技术,指出只要将LED显示单元更改为电热模块,并利用功率控制器件来控制模块的加热功率,就可以再现任意的热图。利用碳纤维增强的高分子复合材料制备了发热模块,并对其物理性能进行了测试,结果表明这种模块完全满足热图再现的技术要求。最后,用64个电热模块、一台笔记本电脑、一台可编程控制器以及24 V蓄电池电源构建了热图再现系统。试验测试表明,这样构建的热图再现系统可以清晰再现目标的热图。这些工作对于可控热红外伪装有很好的参考价值。

For the purpose of controllable IR camouflage, the method reappearing infrared image by temperature controling modular is presented. By comparing LED display technique, it is pointed out that if the LED display module is changed with electric thermal modules ,and the heat power for modules is controlled by programmable power controller, infrared image can be reappeared. The electric thermal module is made of macromolecule material strengthened by carbon-fibre. The experimental test indicates that the module＇s physical performance satisfies with the infrared image reappearing technique completely. Finally,with 64 electric thermal module, a notebook PC, a PLC controller and 24 V storage battery,the infrared image reappearing system is made. Experimental tests indicate that the system can reappear the in- frared image of target vividly. These work will have good referenced sense to controlling infrared camouflage.
