Camouflage is an important indicator of a country's camouflage technology level, and has become a common method for the world's military weapons and equipment to prevent reconnaissance and detection. Camouflage technology mainly measures the background reflection characteristics, and formulates the formula of camouflage pigments or coatings based on the background reflection spectrum characteristic curve to replicate the background; and through the control of color and surface structure, the color and surface structure pattern of the ground object are formed on the target to reduce the contrast with the background, eliminate shadows, cause blur, and change the outline of the target.
In the future battlefield, various thermal infrared imaging reconnaissance equipment will be widely used, so camouflage must be able to resist thermal infrared imaging reconnaissance. Since long-distance cross-regional mobile operations are possible under the conditions of information warfare, camouflage must have the ability to change in time with changes in the activity area, season, weather, etc., so as to achieve a high degree of integration with the dynamic background in the full time domain, so the color-changing camouflage has a broad prospect. Adaptive camouflage is mainly aimed at complex electromagnetic environments. Since the reconnaissance and detection threats faced in the future are changing rapidly, camouflage is required to truly realize the design concept of "same color and same spectrum" to better resist reconnaissance means such as hyperspectral imaging, laser detection, and polarization detection.
At present, the relationship between camouflage development and biology is getting farther and farther. Although some progress has been made, the results are not obvious, and the development level of camouflage has always lagged behind the level of reconnaissance detection. Tracing back to the source, people are surprised to find that natural and natural camouflage is always the best, so re-learning from biology has become the key to solving the current bottleneck of camouflage technology.
In the future, camouflage will surely develop rapidly in several key directions, such as infrared camouflage, color-changing camouflage and adaptive camouflage, as the reconnaissance band expands and the resolution capability improves. The scientific and technological progress in the fields of bionic science, nanotechnology, cognitive neuroscience, and materials science continues. These new technologies have promoted the development of modern camouflage, making the hiding ability of future soldiers no less than that of chameleons.
