Detection and control of unmanned vehicles can be carried out by help of instruments of infrared or radar tracking, acoustic hearing and visually. At the same time the color type camouflage of drones can significantly decrease the effectiveness of visual method of their detection.
In this case the other more acceptable method – method of thermodetection should be applied. It should be noted that the great variety of infrared signatures of existing drones lead to non – accuracy of information receipt from these devices, besides the non-zero probability of detection of plume of emitted high temperature gases does exists. The above said requires utilization of thermo – visual method for detection of drones combining joint utilization of visual and thermal methods of detection. Technically this method should be realized using two – band on board optical systems of detection containing visible and infrared bands. The questions on assessment of effectiveness of thermo visual method for detection of drones with electrochrom camouflage of down surface are considered. The method of thermo – visual detection of drones provided with electron color camouflage. In the article the effectiveness of thermo visual method for high-height on-board detection of low height flying drones provided with electrically controlled electrochrom cover is also analyzed. The rationality condition for effectiveness of operation of systems of thermo-visual detection of drones is determined. The methods for increase of effectiveness of color camouflage of unmanned aerial vehicles are determined. The formula determining the condition of maximum effectiveness of drones color camouflage is given. It is shown that in drones with high infrared signature the electronic color camouflage may give more positive effect. The effectiveness of method of thermo – visual detection of drones with electronic control of color camouflage is estimated.
