| 摘 要： | 为了抑制末制导雷达目标跟踪过程中的角闪烁噪声,对闪烁噪声的统计特性进行了分析,建立了符合其分布的统计模型及系统的状态空间模型,用交互多模型算法解决了角闪烁背景下的目标跟踪问题;并根据该问题的特点,对IMM算法进行了简化.仿真结果表明,用交互多模型方法抑制角闪烁噪声是非常有效的,基于转换卡尔曼滤波的IMM算法比基于扩展卡尔曼滤波的IMM算法具有更高的跟踪精度;简化的IMM算法虽然在跟踪精度上不如基本的IMM.但仍然达到了很好的滤波效果,而且大大降低了计算的复杂程度,是一种更符合工程实际的抑制角闪烁噪声的方法.

| Abstract: | In order to suppress the angular glint noise in target tracking process of terminal guidance radar,the statistic property of the glint was analyzed and the statistic model was built up.State space model of system was built and IMM algorithm was used in target tracking in the presence of glint noise.Besides,IMM algorithm was simplified based on the specialty of this problem.Simulation result demonstrated that:1) IMM algorithm is effective in suppressing angular glint;2) The IMM algorithm based on converted K... |
