Research Progress in Trajectory Prediction forNear Space Hypersonic Vehicle

临近空间高超声速飞行器轨迹预测对其自身制导控制与对其防御拦截均具有重要意义。本文从合作与非合作两个角度对临近空间高超声速飞行器轨迹预测中采用的常用方法进行了分析,在合作飞行器的轨迹预测中,重点结合飞行器预测校正制导过程对解析法与数值法进行了归纳与分析;在非合作飞行器的轨迹预测中,主要分析了基于运动模型预测、基于概率密度预测与基于博弈对抗预测等几种不同轨迹预测方法。最后对轨迹预测的可能研究方向进行了分析。

Trajectory prediction for near space hypersonic vehicle is of great significance to the guidance and intercept.The common prediction methods for near space hypersonic vehicle are analyzed from the cooperation and non-cooperation point.Firstly,for the cooperation vehicle,the analytic method and numerical method are summed up and analyzed combined with the process of aircraft prediction-correction guidance.Then,predictions based on motion model probability density and game antagonism are analyzed for the non-cooperation vehicle.Finally,the possible research directions for trajectory prediction is analyzed.
