空空导弹擦肩发射全向三维可攻击区计算

Calculation of All-Aspect Attack Zone for Air-to-Air Missile Merge

采用推力矢量控制的程序转弯(最小半径)和三维空间比例导引的复合制导方法,实现了空空导弹的擦肩发射时攻击后半球目标,完成全向攻击的能力.基于空空导弹的动力学方程与制导律的数学模型,通过大规模系统的6自由度飞行轨迹仿真计算迭代出了空空导弹的3维可攻击区,分析了影响可攻击区形状与大小的主要因素.数值仿真结果表明,此全向攻击复合制导方法可以实现导弹擦肩发射,并能全向攻击在不同空域作各种不同速度机动飞行的目标.

A composite guidance law with minimum turning radius and three-dimensional proportional guidance was presented for the merge of air-to-air missile.Based on differential dynamic equations and guidance law of air-to-air missile,3D attack zone and 6DOF flight trajectories were calculated.Main factors affecting attack zone shape and size were analyzed.The simulation result shows that by the composite guidance method,the missile merge can be realized to attack the maneuver-flight target with different velocity in different airspace omnidirectionally.
