为解决不同射角下二维修正弹偏离方案弹道时的弹道修正问题,研究二维弹道修正弹在控制力作用下弹轴及质心运动规律,针对基于速度方向修正的制导方法和落点预测制导方法的优缺点提出二维修正弹的复合制导方法,在初制导采用速度方向修正的制导方法,在弹道顶点开始采用落点预测制导算法。仿真结果表明,无论在小射角还是大射角下,该复合制导方法都具有较高的准确度。

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.
