To solve the trajectory correction problem in two-dimensional trajectory correction projectile deviating from the program trajectory at different angles of incidence, the axis and centroid movement law of two-dimensional trajectory correction projectile under the action of control force are studied. Aiming at the advantages and disadvantages of the guidance method based on velocity direction correction and the guidance method of fall prediction, a two-dimensional correction projectile composite guidance method is proposed. Velocity direction correction guidance method is used at the initial guidance, and fall prediction guidance algorithm is use at the ballistic apex. The simulation results show that the combined guidance method has higher accuracy both at small firing angle and at large firing angle.
