摘　　要：滑翔类制导炸弹已经成为要地防空面临的重要威胁,如何精准预测该类型目标轨迹及未来点是现代防空火控解算的关键问题。提出了一种基于姿态估计的滑翔类制导炸弹目标未来点预测方法。首先,在目标现在点估计的基础上,推算出目标姿态坐标系,并在姿态坐标系受力分析的基础上,建立目标机动平面;然后,在机动平面内建立阻力、升力可迭代的动力学微分方程;最后,将机动平面内获取的预测点转换到状态估计坐标系获取最终结果。实验结果表明,相较于传统方法,该方法对目标未来点的预测精度提高了37.2%~65.5%,对滑翔类制导炸弹目标的轨迹预测更加有效。Glide-guided bombs have become an important threat to air defense in important areas.How to accurately predict the trajectory and future point of this type of target is the key problem of modern air defense fire control solution.A method for predicting the future point of glide-guided bomb targets based on attitude estimation is introduced.Firstly based on the estimation of the present point of the target the attitude coordinate system of the target is calculated and the target maneuver plane is established on the basis of the force analysis of the attitude coordinate system.Then the dynamic differential equations in which the drag force and lift force can change iteratively are established in the maneuvering plane.Finally the prediction points obtained in the maneuver plane are converted to the state estimation coordinate system to obtain the final result.The experimental results show that compared with the traditional method the accuracy of future point prediction is increased by 37.2%~65.5%which can be used as a more effective means for trajectory prediction of glide-guided bomb targets.
