摘　　要：Phase change material(PCM) can be used to prepare the infrared false targets for realizing all-weather passive infrared decoy,but its low thermal conductivity is a great blockage to the simulation of the infrared signature of thick metal plates.For that reason,a method of simulating the infrared signature of thick steel plates by thermal conduction enhanced PCM,including the aluminum fins,is proposed.A physical and mathematic model is set up,and the infrared signature simulation of thick steel plate is investigated numerically.The effects of the distribution density and thickness of fins and the thickness of PCM plate on the simulation results are discussed,and the reasonable construction parameters of PCM plates used to simulate the steel plates of different thickness are obtained.Phase change material（PCM） can be used to prepare the infrared false targets for realizing all-weather passive infrared decoy,but its low thermal conductivity is a great blockage to the simulation of the infrared signature of thick metal plates.For that reason,a method of simulating the infrared signature of thick steel plates by thermal conduction enhanced PCM,including the aluminum fins,is proposed.A physical and mathematic model is set up,and the infrared signature simulation of thick steel plate is investigated numerically.The effects of the distribution density and thickness of fins and the thickness of PCM plate on the simulation results are discussed,and the reasonable construction parameters of PCM plates used to simulate the steel plates of different thickness are obtained.
