临近空间高超声速目标跟踪技术研究

由于临近空间高超声速目标具有高速度、高机动的特点,对此类目标的跟踪是一个研究热点问题。提出了一种基于容积卡尔曼滤波的临近空间目标跟踪方法,首先分析临近空间高超声速目标的运动特性,建立了临近空间高超声速目标的运动模型。然后通过三站测得时差信息,实现了对临近空间目标的跟踪。最后,对提出的算法与扩展卡尔曼滤波和不敏卡尔曼滤波进行了综合性能对比分析,并通过仿真结果验证了该算法的实时性有效性。

Near Space Hypersonic Target Tracking Technology Research

Since the near-space hypersonic targets have characteristics of high speed and high maneuverability,research on these kinds of targets is imminent. The algorithm based on the cubature Kalman filter is introduced to track the near -space hypersonic targets. At first,the moving characteristics of near-sapce hypersonic targets are analyzed,and the motion models of the near-sapce hypersonic targets are established in this paper. Then,the time differences of arrival of three stations to track the near-space hypersonic targets used. At last,the comprehensive performances are analyzed among introduced algorithm,the excented Kalman filter and unscented Kalman filter. Simulation results show the real time performance and effectiveness of presented algorithm.
