Abstract
The high-speed anti-ship missile might encounter a challenge in the terminal phase if there are mixed targets, including false and true ones. There is only a quite short time to take action after the onboard radar can distinguish which targets are true or false. In this study, a tunable acceleration feedback gain is used to realize a unique integrated guidance and control scheme in a natural way by maintaining advantages of the traditionally practical proportional navigation and three-loop acceleration autopilot without introducing additional dynamics as the existing methods in the literature. The gain range can be determined using a numerical calculation scheme. The adjoint method is employed to reveal the advantage of the tunable gain and can then obtain the optimal gain. The proposed method can achieve a trade-off between the effective navigation gain and the settling time of the autopilot during the integration. Extensive simulations are performed to validate the appealing discovery. This philosophy offers guideline for the renovation of existing anti-ship missiles.
