摘　　要：伪装技术和红外探测技术的迅速发展,双波段热像仪能够很容易地识别出传统热隐身涂层下的目标。为了更好地实现隐身,从红外融合思想出发,提出了热红外相变-降温复合隐身涂层,并对涂层的作用原理及可行性进行了论述。复合涂层的面层(降温涂层)强调对背景辐射的吸收越少越好;底层(相变涂层)则强调目标的表观温度与背景温度相对一致。实验结果表明,该复合隐身涂层同时具备调节发射率和温度的功能,不仅能对付双波段热像仪的侦察,而且适用于单调背景或复杂背景下的伪装。With the rapid development of camouflage technology and infrared detect technology, targets under the traditional thermal stealth coatings will be identified by dual-bands detector easily. For the sake of accomplishing better stealth, thermal infrared PCM temperature reduction composite coating based on the design idea of IR fusion is proposed and the principle and feasibility of the coatings are addressed. For the surface coating, the less absorption to background radiation the lower temperature the coating has; and for the PCM coating, the apparent temperature needs to be adapted to the surrounding temperature. Experiment results show that this thermal stealth composite coating has the ability of accommodating its emissivity and temperature, and it can not only resist the dual-bands thermal imaging system, but also be applied in single or complicated background.
