Research And Design Of Wide Band Adaptive Camouflage

Wide-band adaptive camouflage showing-fake devices is a a kind of device which can be realized in the infrared camouflage device and have false complex functions, its working principle is able to make the necessary adjustments according to the ambient temperature, illumination change by temperature regulation technology, spectrum, so that their own heat radiation and optical characteristics matching with the environment,achieving the purpose of camouflage; and based on the camouflage technology, on the basis of the related parameter adjustment, you can achieve the function showing false. Currently, the composite camouflage has become an important development direction of camouflage.Combined domestic and international trends and related engineering background, wide-band adaptive camouflage shows fake devices were studied. This device is mainly used two camouflage techniques:based on near-infrared spectral brightness adjustment technology and far infrared radiation based on temperature regulation technology. First, the paper shows a wide band adaptive camouflage background and means of false means the physical model design are introduced, wherein the physical model includes adjustment model spectra and temperature adjustment model; then, the paper introduced the hardware design and software algorithm means design, the main function of the device masquerading shown fake design ideas and implementation, temperature control algorithm and spectrum regulation algorithm were introduced, in particular, into the hardware part of the outside temperature sensing and optical information detection module, and a detection signal processing for driving the display control module and display fake camouflage function display module shown in three blocks, including through the control software section based PID temperature control algorithm and regulation algorithms two algorithms based on spectral brightness adjustment; Finally, the paper describes the device experiments and analysis, including apparatus shown in false test and camouflage function tests successfully simulated temperature spots shown false and adaptive camouflage, but also prove the feasibility of device design.
