为实现全向攻击,红外空空导弹需要解决全向制导律设计问题。基于虚拟目标算法和大离轴制导律,提出了一种三维空间全向制导律。全向制导律与大离轴制导律具有统一的形式,但越肩发射初始转弯段和末制导段的制导信息来源不同。针对几种典型攻击条件进行了数字仿真。分析表明,全向制导律具有良好的越肩发射或擦肩发射性能,能够应用于红外空空导弹全向攻击制导设计。

To satisfy the demand of omni-directional attack, omni-directional attack guidance law design is urgently needed for infrared airto-air missile. A kind of omni-directional attack guidance law based on virtual target method and large off-boresight guidance law was designed and presented in 3-D space. Performance of omni-directional attack guidance law was studied according to numerical simulation in several scenarios. Having the same form with the large off-boresight guidance law, omni-directional attack guidance law uses the same information with different sources under the condition of "over the shoulder" or "merge". Performing well under the conditions of "over the shoulder" or "merge", omni-directional attack guidance law is demonstrated to be powerful and can be applied in omni-directional attack guidance design for infrared air-to-air missile.
