Abstract

Based on the principle of infrared target system, the emissivity and reflectivity of the coating material of the target plate of the infrared target system are studied in depth. The relationship between the emissivity, reflectivity and light wavelength of the target is discussed in this paper. First, 50 target plates are selected and the diffuse reflectance of 1.06 μm laser is measured. The experimental results show that the minimum reflectivity is 0.202 and the maximum reflectivity is 0.217, which is in the range [0.2,0.3]. The average value of reflectivity is 0.20886, and the measurement error is in the range [-0.00686, 0.00814]. Then, the non-uniformity value of each measured value is calculated, the maximum value is 3.89%, less than 7.5%. Finally, the emissivity of the coating material is measured in the wavelength range of 2.5 μm ~ 13.5 μm, and the minimum value is 0.869, better than 0.7. At the same time, four kinds of coating materials are compared and the results show that the coating materials in this paper had higher emissivity. The infrared target system can model all kinds of infrared targets, which provides a method for target attack experiment.
