Abstract: With the unique advantages of strong maneuverability, high efficiency-cost ratio, and unmanned characteristic, the unmanned aerial vehicle (UAV) equipped with the photoelectric countermeasure system is applied to the unmanned electronic warfare and seize the initiative on the battlefield, which is the hot spot of the current development of photoelectric countermeasure. The application of photoelectric countermeasure technologies such as photoelectric reconnaissance warning, electronic suppression and jamming, and photoelectric stealth in UAV platforms was analyzed. It focused on the development trend of photoelectric technology in UAV platforms in terms of miniaturization, lightness and standardization. The prospect of UAV swarm technology and intelligent photoelectric countermeasure system to play the role of photoelectric countermeasure in the future complex war environment was looking forward.
