Abstract To conduct the anti-cluster UAV (unmanned aerial vehicle) air defense system demonstration, this paper constructs a system capability evaluation index system and a system effectiveness evaluation index system from the per-spective of system capability and system effectiveness. The TOPSIS (technique for order preference by similarity to an ideal solution)method and simulation method are used to evaluate the system capability and system effectiveness of anti-cluster UAV equipment, and then complete the evaluation of contribution rate of anti-cluster UAV equipment system. An example is used to verify the feasibility of the method, which can support the demonstration and research of the equipment to a certain extent.
