装甲隐身涂层940nm双向反射分布函数

摘要

红外隐身涂层的激光隐身性能测试侧重于外场整车后向反射率测量,其测量精度有限.针对这-缺点,按照国军标制作红外隐身涂层样品,在实验室条件下,用特定激光波长(940nm)激光作为照射源,以聚四氟乙烯标准白板为参考标准,采用相对法测量不同红外发射率隐身涂层样品的双向反射分布函数(BRDF),系统测量精度优于7%.误差分析表明测量结果可信.%The present laser camouflage performance measurrnent of infrared camouflage coating focuses on the back reflectivity of field vehicle measurement, and the accuracy of it is limited. Aiming at the shortcoming on this method, a sample of infrared camouflage coating of the military standard was manufactured under laboratory condition. In this measurement, the definite laser wavelength (940 nm)was used as the illumination source, PTFE standard whiteboard as a reference standard, and the relative measurement method was taken to measure the BRDF of different infrared emissivity. The measurement accuracy was superior to 7 ％. The error analysis testified the credibility of measurement results.
