Considering the cooperative guidance law of multiple vehicles in detection configuration

For the missing relative distance guidance problem, a cooperative guidance law for multiple vehicles considering the detection configuration is proposed. Firstly, for the missing relative distance problem, the relative distance is obtained by introducing the cooperative detection of multiple interceptors, and secondly, considering that the detection configuration of interceptors affects the detection error, the guidance law introduces a cooperative ranging error model related to the line of sight separation angle of two interceptors, and adopts the optimal control theory to design an optimal guidance law that can modulate the line of sight separation angle of two interceptors, which can separate the trajectories of two vehicles to increase their It can separate the trajectories of the two vehicles and increase their line-of-sight separation angles to reduce the two interceptors' cooperative detection errors. After Monte Carlo simulation, the proposed guidance estimation method is compared with the traditional guidance estimation method, and the results show that the proposed guidance estimation method has obvious advantages in detection and interception performance compared with the traditional method.
