一种增大空地导弹落角的新制导律

A New Guidance Law for Air-to-Ground Missiles at Enlarged Impact Angle

为发挥空地导弹侵彻战斗部的威力,提高目标毁伤效果,引入了一种新制导律"弹道成型"制导律,对导弹的末端落角进行约束。通过与比例导引和过重力补偿比例导引进行对比,建立数学模型,进行数字仿真,分析了新制导律在增大导弹落角方面的优点。仿真结果表明,在较低的平飞弹道约束条件下及过载要求范围内,"弹道成型"制导律能以期望的落角命中固定或机动的目标,具有较大的工程实际应用价值。

To improve the lethality of penetration warhead of air-to-ground missiles, a new guidance law of ＂Trajectory Shaping＂ was introduced to restrict the missile＇s impact angle. By comparing the ＂Trajectory Shaping＂ with proportional navigation and over-gravity compensation guidance law, an mathematic model was established for simulation, and the advantages of new guidance law for increasing the missile impact angle were analyzed. The simulation results indicated that the new guidance law can make the missile hit the immobile or maneuvering targets at desired impact angle under the condition at relatively low trajectory and within the maximum acceleration.
