The attacking UAVs have slow response speed in the battlefield and have difficulty to support the tactical unit.To solve the problem,a small attacking quad-rotor UAV system is proposed.The system can be carried by one soldier,which is adaptive to a variety of operational conditions owing to the high stability of the four rotors.Combined with image processing technologies,the system can help soldiers analyze the battlefield situations,quickly identify enemy units and finally launch attacks.The system can meet the operational requirements of army soldiers under the modern operational conditions,and provide more possible operational methods for army′s tactical units.
