The modern battlefield presents new challenges for the traditional methods of camouflage.现代战场对传统的伪装技术提出了新的挑战，Modern sensors are able to resolve very small differences between targets and background, and a traditional static camouflage solution will only maintain a close enough match to its environment if the environment also remains static. 在环境为静态条件下，现代传感器能够辨别出目标与背景之间的细微差异 ,传统的静态伪装方法只能通过保持目标尽可能与环境相匹配来达到隐身目的To maintain low detectability in a changing environment, camouflage systems must adap伪装系统还必须 适应 在一个不断变化的环境中保持目标的低可探测性， 。

This research demonstrates concepts of adaptive camouflage for a light armoured vehicle (a Canadian Coyote) in a desert environment.本次研究论证了在沙漠环境条件下的一个轻型装甲车辆自适应伪装技术的概念 (加拿大狼)Three techniques are investigated. A heat shield cover to reduce thermal signature and solar heat transfer into the vehicle, 并对其中的三项技术做了相应研究即通过热屏蔽罩以减少热信号识别和太阳辐射热能向装甲车辆上 转移electro-chromic cells to simulate a chameleon-like behaviour in the visual spectrum, 用电致变色传感器来模拟变色龙的视觉效应，and active thermal cells to create dynamic disruptive thermal patterns on the heat shield. 并在热成像系统上显示出热屏蔽罩的动态热能分布图像。

The overall objective is to create a system to reduce conspicuity across the visual and infrared spectrum by disrupting the vehicle silhouette and minimising the difference between the background and vehicle characteristics. 最终目的是建立一个在可模糊装甲车辆的轮廓和减小车辆特 征与其背景之间的差异，降低目标在视觉和红外光谱中的醒目性This paper presents results from recent proof-of-concept testing 本文介绍了近期概念验证测试的结果绪论 The goal of camouflage systems is to reduce the vulnerability of platforms, installations and personnel to detection and identification. 伪装系统的目的是减少平台，设施和人员的弱点以避免被发现并被识别。

This task has become increasingly difficult as sensors on the modern battlefield become more sophisticated and able to image targets with increasing sensitivity in multi-spectral bandwidths.这个任务已经变得越来越困难，因为在现代战场上的传感器变得越来越复杂，在多频谱带 宽中对目标图像的灵敏度也得到了提高Land vehicle camouflage is a particular challenge.陆地车辆伪装是一个特殊的挑战The range of different types of sensors land vehicles may expect to encounter requires that camouflage systems be multispectral in effect. 陆地车辆可能会遇到不同类型的传感器的探测， 这就需要伪装系统在多种频谱范围内具有伪 装效果The need for mobility limits the obstruction of certain readily identifiable characteristics such as wheels and engine exhaust.需要限制一 些容易 识别的 移动特 性，如车 轮和发 动机排 气。

Additionally, expected engagement ranges can be quite short for many modern operations, 此外，在许多现代的操作上预设的耦合距离可以很短，therefore it is more and more common to see performance goals for vehicle camouflage systems setting desired detection ranges of less than 1 km.因此车辆伪装系统设定的检测范围在不到 1 公里是很容易就能发现目标特征For camouflage systems to be effective against modern imagers at these close ranges, they must very closely match their environment.对于伪装系统， 他们必须非常密切地与所处环境相匹配， 并有效地对抗近距离内的现代成像，This means reducing the contrast of the vehicle against the background to very low levels. 这意味着车辆与背景对比度需要降低的一个很低的水平。

Maintaining a low enough contrast is difficult for traditional static camouflage systems, 传统的静态伪装系统很难使目标具有做够低的对比度，due to the fact that the environment of a vehicle is constantly changing while the camouflage material properties are fixed. 在车辆所处环境在不断变化，而伪装材料特性则是固定的A vehicle will move from place to place, changing its background as it goes. But, even when stationary, changing solar and weather conditions create a constantly varying background, which limits the effectiveness of static camouflage solutions[1]. 背景会随车辆的移动而发生改变， 即使在车辆在静止情况下， 太阳辐射强度和天气条件的变 化也会导致背景发生改变，这一事实就限制了静态伪装技术的有效性 [1] 。

Static camouflage systems are unable to respond to these changes well enough to consistently remain below the maximum acceptable contrast. 静态伪装系统在这些变化条件下无法很好的保持目标具有低于对比度响应的最大允许值 Therefore, to meet this challenge, camouflage systems for the future must become more adaptive, responding actively to changes in their environment. 因此，要应对这一挑战，未来的伪装系统必须具有更广适应性以积极应对变化的环境 Responding appropriately to maintain low detectability against common sensors requires being able to change the apparent surface characteristics individually in both visual and thermal domains.为应对普通探测器的探测， 使目标保持低探测性， 这就需要对目标的表面进行处理以改变其 视觉和热区特性This means that new camouflage system concepts are required that can actively alter their temperature characteristics and their colour separately in response to their environment.这意味着，新的伪装系统的概念要求能够迅速改变目标的温度特性和颜色以响应环境的变 化。
