Cooperative polynomial guidance law with collision avoidance and flight path angle coordination

In this paper, a cooperative polynomial guidance problem is investigated against a maneuvering target based on trajectory parameterization with collision avoidance and flight path angle coordination. To this end, a polynomial reference trajectory satisfying the initial and terminal constraints is introduced with its highest-order coefficient chosen as the guidance gain. Then, a safe distance criterion is enforced to coordinate parameters of the missiles for collision avoidance along the reference trajectories. Finally, the cooperative guidance law is developed by ensuring a smooth tracking of the polynomial reference trajectory. Numerical simulations verified performance of the proposed guidance strategy.
