带动力机动弹头制导方法研究

Research on guidance algorithm for mobile warhead with power

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。

To solve the guidance problem of a mobile warhead with power,a series of guidance algorithms for descent and pull-out phase,horizontal flight phase and diving attack phase are proposed.In descent and pull-out phase,the program descent and arc pull-out guidance laws are adopted,which make sure the accurate horizontal altitude is achieved.In the horizontal flight phase,the altitude maintenance guidance law and bank-to-turn to pass the waypoints guidance law based on geometric method are designed,which aimed at improving the detecting precision and avoiding the danger areas.In the diving attack phase,multi-attack modes are given based on the basic guidance law.The guidance algorithm for each phase is validated by three dimension-of-freedom simulation,and it shows that the proposed guidance laws are practicable.
