Abstract : "In order to meet the needs of high-precision guidance for missile-guided maneuvering targets in the
presence of towed bait interference, this paper proposes a new guidance strategy based on heading angle method
and parallel approaching method. Its main idea: a suitable angle is determined by heading angle method which of
the missile trajectory is above that of the towing bait. Meanwhile, the accurate interception of missiles to targets
is guaranteed by parallel approaching method. Firstly, system models of missile and target with towed decoy are
established. Then, considering unknown bounded system disturbances, a controller is given based on sliding mode,
back-stepping method. Furthermore, to solve the input saturation problem, an anti-saturation controller is given
using adaptive and back-stepping sliding mode methods. Finally, strict proofs of the two controllers are given using
Lyapunov stability theory, and simulations are carried out to verify the effectiveness of the two controllers."
