Abstract
Based on the centralized leader-follower framework, a novel cooperative guidance strategy is proposed to implement the fire-and-forget attacks of seeker-less missiles in which the motion information of a maneuvering target and the strict requirement on the convergence time of the position are not required for the seeker-less missile. First, based on the motion states of two seeker-guided missiles, a virtual target (a point or line) that can certainly arrive at or cover the maneuvering target is carefully selected. Then, two cooperative guidance laws corresponding to the point and line virtual target are derived based on the consensus theory and dynamic inversion control, respectively. One of the guidance laws can implement the simultaneous attack of multiple missiles by employing both normal and tangential overloads, while the other is more practical to be employed as it only controls the normal overload of the seeker-less missile, even though the simultaneous attack cannot be implemented. Simulations are conducted, and the impact of the guidance parameters on the guidance performance is also studied. The results demonstrate the effectiveness of the proposed cooperative guidance laws.
