For the purpose of controllable IR camouflage,the method reappearing infrared image by temperature controlling 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 infrared image of target vividly.These work will have good referenced sense to controlling infrared camouflage.
