摘要: 为了提高临近空间高超声速滑翔目标的跟踪精度,基于目标的航迹倾角变化规律建立了一种新的机动模型。为了在雷达测量直角坐标系下估计目标的位置和速度,分析了目标的弹道剖面角,基于航迹倾角变化率和倾角变化率有相近似的变化规律,提出用倾角代替航迹倾角,将倾角变化率描述为零均值正弦自相关随机过程建立角度域的Markov模型,然后将角度关系映射到位置维度建立空间模型。为了使得系统总体状态模型线性,将模型拆分为前端的角度子滤波器和后端的位置子滤波器,由角度滤波器驱动位置滤波器联合跟踪滤波。通过仿真设置了模型的参数,实验结果表明其模型具有更好的跟踪精度。

Abstract: To improve the tracking accuracy of the hypersonic gliding target in the near space, a novel maneuvering model is established based on the change rule of flight path angle. In order to estimate the position and velocity of the target in the radar measurement coordinate system, the angle of the target's trajectory profile is analyzed. Because of the similar change rule between the change rate of flight path angle and that of the inclination angle, it is proposed to use the inclination angle instead of the flight path angle for establishing the maneuvering model. The change rate of inclination angle is described as a zero mean sinusoidal autocorrelation stochastic process and a Markov model is established. The angular relationship is mapped to the positional dimension for establishing a spatial model. To make the system state model linear, the model is divided into the front-end angle sub-filter and the back-end position sub-filter, and the angle sub-filter drives the position sub-filter for tracking. The parameters of the model are set through simulation. The experimental results show that the model has better tracking accuracy.
