变形迷彩伪装的技术指标分析

Analysis on the Technical Items of Distortion Pattern Painting

介绍了我国国家军用标准中与变形迷彩伪装有关的技术指标,并从侦察制导技术的发展出发,讨论了现有国军标需要扩展与补充的内容。建议光学伪装指标中增加对抗高光谱侦察的内容;建议斑点尺寸形状技术指标以面积、周长、伸长度、分散度和整体凹度等特征值给出量化的规定;建议重视热红外伪装相关技术指标的建立。实验表明热图迷彩效果不单纯由迷彩斑点的发射率决定,建议采用日间无风强日照条件下和夜间少云条件下斑点间辐射温差来评价热迷彩性能。

The technical items about distortion pattern painting in Chinese military standards are introduced. Based on the development of reconnaissance and homing technology, some supplementary items are suggested to perfect the standards. The items countering hyperspectral reconnaissance are put forward in visible and near infrared band. The characteristic vector that composed of area, girth, dispersing ratio, elongation ratio and whole concavity is proposed to describe the spot shape. The establishment of thermal IR camouflage technical items receives great concern in this paper. Experiment showed that the emissivity difference alone is not enough for the forming of thermal pattern spots. The apparent temperature difference between the spots is utilized for evaluating the efficiency of thermal pattern under the condition of strong sunshine, windless in daytime and cloudless in nighttime.
