| 摘 要： | 针对目标跟踪系统具有强非线性非高斯的特点,提出了一种强跟踪粒子滤波(STUPF)算法.该算法将无迹卡尔曼滤波器(UKF)与强跟踪滤波器(STF)相结合作为粒子滤波提议分布,具有在线调节滤波增益阵,提高滤波器跟踪突变状态的能力.在给出闪烁噪声统计模型的基础上,将STUPF应用在几种典型目标运动模型跟踪系统中,并同UKF和...

| Abstract: | Due to strong nonlinear and non-Gaussian nature of the target tracking system,a strong tracking particle filter(STUPF) algorithm is presented.The algorithm adopts a new proposal distribution combining the unscented Kalman filter(UKF) with the strong tracking filter(STF),the filter gain matrix can be adjusted on line according to the change of innovation,and the ability of tracking saltatory state is improved.The STUPF is applied to track several kinds of typical target moving model tracking systems based on... |
