Aiming at the problem of multi-aircraft game confrontation under the condition of network com-munication delay,a cooperative differential guidance law is proposed.Firstly,based on the differential countermeasure theory on the basis of the traditional norm-type performance index,the weight coefficient is designed to increase the weight coefficient and a collaborative differential guidance method is derived under"bang-bang"structure.Secondly,by considering the time delay in the network communication among in-terceptors,the target acceleration value obtained is an attainable domain instead of an accurate value,and the target acceleration range can be reduced by introducing the observed target acceleration direction infor-mation,and the error between the target acceleration and the target actual acceleration can be reduced,thus,the guidance precision of the interceptor is improved.Finally,numerical simulation is implemented to verify the effectiveness of this algorithm,and the simulation results show that this guidance law does not need to assume the maneuvering law of the target in advance and can effectively intercept the maneuvering target under the information time delay.
