As an important part of information operation, electro-optical countermeasures bring an extraordinary operational effectiveness among modern wars and advance constantly. This article will illustrate the recent development feature and tendency of electro-optical countermeasures technology abroad and introduce the development actuality of main electro-optical countermeasures equipment abroad. Introduces develop high performed and high availability directed energy weapons, emphasis entity destroy; enthusiastic attempt to new technology and system on electro-optical countermeasures field; all-in-one and miniaturization trend, simplify operation; establish a perfect electro-optical countermeasures simulation and evaluation system. And also puts forward the development presumption of conducting basic research, improving the availability and commonality of equipment, carrying research on anti-jamming simulation technologies and etc.
