| 摘 要： | 提出一种改进的强跟踪卡尔曼滤波算法，应用于ＧＰＳ动态定位滤中获得明显效果，首先采用描述机动载体运动的“当前”统计模型，建立了一咱新的ＧＰＳ动态定位扩展卡尔曼滤波模拟及其适应算法，然后，为了进一步提高滤波器的动态性能，改进了周东华等提出了的强跟踪滤波器，大大提高了ＧＰＳ动态定位位扩展卡尔曼滤器的跟踪能力。

| Abstract: | A modified strong tracking Kalman filtering algorithm is proposed, and the performance of GPS kinematic positoning filter is improved for moving vehicles by use of the filtering algorithm. At first, by means of a current statistical model and adaptive algorithm for estimatimg maneuvering tragets, a new extended Kalman filtering model is built to estimate the position and velocity of moving vehicles, and the adaptive algorithm of the extended Kalman filter is presented. Then in order to improve the dynamic performance of the Kalman filter, an effective modified strong tracking Kalman filtering algorithm is introduced in detail. |
