Abstract:

To achieve the cooperative attack against the same target for multi-missiles, according to homing guidance geometry, a new cooperative guidance law is devised with impact time control and seeker’s field-of-view(FOV) limit. To derive the guidance command of the proposed law, a polynomial function is introduced to satisfy the terminal impact time control. By adding a feedback of seeker’s FOV function, the proposed guidance law can achieve impact time control and seeker’s FOV limit at the same time. When the limits of the maneuvering acceleration and the seeker’s FOV are defined, the missile trajectory can be determined by the initial missile parameters, then the minimum and maximum cooperative time can be calculated. Simulation results show the validity of the proposed guidance law.
