【摘要】：为了给基于预测命中点法的高超声速飞行器中制导拦截提供先验知识,提出高超声速飞行器的轨迹预测方法。首先,给出高超声速环境下与目标姿态近似线性的气动参数;其次,针对气动参数作控制量的运动模型,设计自适应交互多模型(IMM)跟踪算法,并进行性能有效性验证;然后,根据气动参数特性和目标假设机动方式,设计基于最小二乘拟合的轨迹预测方法。通过对目标轨迹进行跟踪和预测仿真,预测100s的位置误差均小于5km,速度误差均小于100m/s,结果表明基于自适应IMM的轨迹预测方法对有规律机动的目标进行轨迹预测,效果良好。
[Abstract]:In order to provide a prior knowledge for the guided interception of hypersonic vehicle based on predictive hit point method, a trajectory prediction method for hypersonic vehicle is proposed. The aerodynamic parameters which are approximately linear to the target attitude in hypersonic environment are given. Secondly, an adaptive interactive multi-model (IMM) tracking algorithm is designed for the motion model in which aerodynamic parameters are controlled, and the effectiveness of the algorithm is verified. Then, according to the aerodynamic parameters and the maneuvering mode of the target hypothesis, a trajectory prediction method based on least square fitting is designed, and the tracking and prediction simulation of the target trajectory is carried out. The position error and velocity error are less than 5 km and 100 m / s respectively. The results show that the trajectory prediction method based on adaptive IMM is used to predict the trajectory of the target with regular maneuvering. The effect is good.
