为解决一种带动力机动弹头的制导问题,给出了弹头在下降拉平段、平飞段、攻击段的制导方法。在下降拉平段,采用程序转弯下降与基于几何法的按圆弧拉平制导律结合的方法,使终端精确达到平飞段所需的高度。在平飞段分别给出了高度保持以及侧向转弯过航路点的制导律,以提高制导探测精度并避开威胁区域。攻击段在基本制导律设计基础上给出了多种攻击方式。各制导方法均通过三自由度弹道仿真得到验证,具有较强的工程实用性。
In order to solve the guidance problem of a maneuverable warhead, the guidance method of warhead in the descend leveling stage, flat flight stage and attacking stage is given. In the descending flat section, the program turns the descent and the geometric method based on the arc leveling guide method combined to make the terminal accurately reach the required level of the flat flight. Guidance law of altitude preservation and lateral turn waypoints are given respectively in Ping-Fei Section to improve the guidance detection accuracy and avoid the threat area. The attack segment gives a variety of attack modes based on the basic guidance design. The guidance methods are verified by three degrees of freedom ballistic simulation, with strong engineering practicability.
