Aiming at the angle handover of the compound guidance for the over-the-horizon ship-to-air missile, a new solution model of the antenna azimuth and elevation pointing angle of the seeker is put forward by setting a new antenna's rotation and projecting the sight angle vector to the corresponding rotation plane. And applying the method of covariance analysis, the error model of the antenna pointing angle of the seeker is presented. Simulation results validate the correctness of the presented solution model of the antenna pointing angle of the seeker and the effectiveness on reducing the pointing angle error.

Aiming at the ship-air missile intercepting the low target, the three-dimensional relative motion between missile and target was established. The high maneuverability of the target and the measurement noise of seeker measuring line of sight(LOS) angular rate were considered, and it was also considered that terminal guidance should be carried out in three-dimensional space. The relative motion model of missile intercepting target was constructed, and the relative-velocity deflection-angle was chosen as the purpose to be zeroed. A variable-structure three-dimensional terminal guidance with strong robustness was designed based on the theory of variable structure, and the model of the guidance instruction solution was presented. The simulation result not only verifies the accuracy of solution model, and it also shows that the robustness of the designed three-dimensional variable-structure terminal guidance law is much better than that of the traditional three-dimensional terminal guidance law.

For a class of strick feedback nonlinear systems with guaranteed prescribed performance, a backstepping controller is designed. The prescribed performance means that the tracking error should converge to an arbitrarily predefined small residual set, with convergence rate no less than a prespecified value, exhibiting a maximum overshoot less than a sufficiently small prespecified constant. A performance function and an output error transformation are introduced to transform the original 'constrained' system into an equivalent 'unconstrained' one. Based on the Lyapunov stability theory, a backstepping controller is designed and the system is stable according to the stability analysis. The simulation results show the correctness of proposed scheme.
