N2 - This paper presents a cooperative guidance law which can prescribe the impact time and ensure the seeker to lock on the target. Firstly, taking the initial state of missiles relative to the target as a reference, the role of missiles can be divided into a leader and followers. Secondly, a prescribed impact time guidance law considering seeker's field of view (FOV) is designed for leader, which realizes finite time convergence of impact time error. A distributed cooperative guidance law is proposed for followers to ensure that the target is always in the seeker's FOV while followers are tracking the leader's state. Furthermore, in order to avoid the singularities of guidance law, a two stage guidance law conversion strategy is proposed to ensure the stable operation of the missile cooperative system. Finally, numerical simulations are utilized to validate the effectiveness of the proposed method.
