一、问题的提出阴影是发现和识别目标的重要特征之一,因此,在目标伪装的隐真示假中,如何处理好阴影就成为伪装工程不可忽视的内容之一。六三年我国曾对××铁路桥(全长555.4米,共19跨)进行过反可见光侦察的伪装试验,试验中为了摸拟一跨桥面被炸毁的伪装效果,除了采用假目标伪装破坏现场外,还必须在隐蔽掉真桥桥面的同时隐去其阴影,否则将会由于阴影的存在而使伪装功亏一篑。为此,当时采用大型倾斜遮障掩盖掉阴影(使阴影投射在遮障下面),然后再将遮障面伪装成现地背
First, the shadow of the issue is one of the important features of the discovery and identification of targets, therefore, in the target of camouflage hidden in the fake, how to deal with the shadow has become a camouflage project can not be ignored. In 1960, China conducted a camouflage test of anti-visible light reconnaissance against the XX Railway Bridge (total length of 555.4 meters and 19 spans). In order to simulate the disguise effect of a bridge deck being blown up and destroyed, Destroy the scene, but also must be concealed off the true bridge deck at the same time hidden its shadow, otherwise it will be due to the presence of shadows and disguised lost. For that purpose, the shadow was then masked with a large tilt mask (so that the shadow cast under the mask) and then the mask was camouflaged as the current back
