空空导弹高抛弹道复合制导律研究

为了提高中近程空空导弹的有效射程，针对导弹特点，提出高抛弹道复合制导律。该制导律在初制导中加入纵向预置抛射角以提高导弹弹道，中制导以修正最优比例导引对弹道倾角进行修正，使得导弹各项指标满足末制导比例导引的交班需求。经多种典型弹道仿真研究，该制导律能够有效增加导弹射程并完成多种机动目标的攻击。该制导律算法简单可行，可用于中近程空空导弹技术升级。

Study of a parabola-trajectory compound guidance law for air-to-air missile

To increase the effective attack range of the short/medium range air-to-air missile,a parabola-trajectory compound guidance law is studied.The guidance law uses the beforehand adding angle in the initial stage to increase the height of the trajectory.In the midcourse guidance,the optimal modified proportional navigation (PN) is taken for the correction of the velocity heading angle to satisfy the handover requirements between midcourse and terminal PN guidance.By the simulation of several representative trajectories,the guidance law is validated.It increases the missile's attack range effectively and suits for the attack of maneuver targets.The guidance's algorithm is simple and feasible,which can be used in the missile's technical upgrade.
