摘要
为研究发射率对装甲车辆红外探测的影响,在充分考虑目标辐射、背景辐射以及目标对背景的反射辐射基础上,建立了表观温差数值计算模型,采用试验验证了模型的准确性。采用MATLAB编制了数值仿真界面,分析了在主要红外探测波段上目标发射率对表观温差的影响。采用理论和试验结合的办法研究了相同探测距离下探测概率和相同探测概率下探测距离这二者与温差的关系。结果表明:在远红外探测波段,装甲车辆发射率对表观温差的影响更为明显,在目标发射率较低的情况下,甚至会导致出现表观温度为负值,进而造成较远的探测距离;相较于单纯地降低目标与环境的温差,采用低发射率的隐身涂料等技术措施,能够显著地降低探测概率,提高隐身效果。该研究能够为装甲车辆的隐身设计提供理论参考。
In order to study the influence of emissivity on infrared detection of armored vehicles.On the basis of fully considering the target radiation,background radiation and the reflected radiation from the target to the background,a numerical model of apparent temperature difference was established,and the accuracy of the model was verified by experiments.The numerical simulation interface was compiled by MATLAB,and the influence of target emissivity on the apparent temperature difference in the main infrared detection band was analyzed.The relationship between the detection probability and the detection distance under the same detection distance and the temperature difference was studied by combining theory with experiment.The results show that in the far-infrared detection band,the impact of the emissivity of armored vehicles on the apparent temperature difference is more obvious.Even when the emissivity of the target is low,the apparent temperature will be negative,resulting in a longer detection distance.Compared with simply reducing the temperature difference between the target and the environment,using stealth coatings with low emissivity and other technical measures can significantly reduce the detection probability and improve the stealth effect.This research can provide theoretical reference for the stealth design of armored vehicles.
