As high-powered laser weapons continue to mature,the battlefields faced by medium/small unmanned aerial vehicle (UAV) are increasingly threatened.In order to further improve the battlefield survivability of medium/small UAV,it is necessary to study the strategies of medium/small UAV to defend high-powered laser weapons.Firstly,analyzes the current development trend of high-energy laser weapons;secondly,gives the composition and operational principles of high-energy laser weapons.On this basis,the constraints imposed on the application of high-energy laser weapons in battlefields are analyzed.Finally,a targeted strategy is proposed for medium/small UAV against high-powered laser weapons,and the key technology paths for implementing these strategies are analyzed.
