无人机机载导弹攻击区目标优化仿真与研究

A Fast Calculation for Attack Area of UAV Airborne Missile

在无人机机载导弹攻击精度优化的研究中,由于无人机机载导弹受舵机延时、过载、发动机点火和视线角等因素的制约,约束条件复杂,而且攻击区受环境影响显著,不仅与自身的飞行特性有关,也与目标的运动特性有关,因此计算复杂而且精度低。采用黄金分割法,建立了基于多种约束条件的目标优化系统,得到了攻击区的远、近距离边界;并进一步研究了无人机与目标在不同飞行高度、高度差和目标的机动过载对机载导弹攻击区的影响。结果表明,上述方法提高了无人机机载导弹攻击区的计算精度,降低了边界搜索次数,为提高导弹攻击精度提供了科学依据。

UAV airborne missile is constrained by driving delay of rudder, overload, engine ignition and line of sight angle and other factors, and the attack area is affected significantly by environment. It is not only related with the flight characteristics of itself, but also with the motion characteristics. Therefore, the computation is complex and the precision of the attack area is low. Using the golden section method, a mathematic model of computing attack area with limited condition was built and far attack area and near attack area were calculated. And further researches on UAVs and targets in the effect of different flight height, large difference of elevation and maneuver overload were car- ried out at the attack area. The results show that this algorithm can improve the precision of the attack area and de- crease the boundary search times.
