Aiming at the problem that the geometric configuration of multi-aircraft co-intercepting a maneuvering target will affect the cooperative detection and guidance effectiveness, the cooperative detection and guidance are considered uniformly. Based on the optimal control theory, an integrated design method of the cooperative detection and guidance considering the measurement configuration is proposed. Firstly, the cooperative intercept model is established based on the relative kinematics, kinetic equation of the aircraft and double LOS co-detection principle. Secondly, the separation angle parameter is introduced in the guidance design process to modulate the co-detection geometric configuration and reduce the relative distance detection error, so as to enhance the synergistic detection effectiveness throughout the guidance. Then, the relative distance of the co-detection is applied to solving the time-to-go and guidance law. Based on the optimal control theory, the integration design of the cooperative detection and guidance is achieved. Simulation results show that in the case of different maneuvers of an evader, compared with the augmented proportional navigation, the proposed method has obvious advantages in cooperative detection and guidance process.
