摘　　要：文章将高动态目标的运动状态分为匀速运动、匀加速运动、转弯模型等状态模型,采用估计目标当前运动状态进而在多个模型中自适应切换运动状态模型的形式实现高动态目标的导航定位,提升卫星导航终端在高动态条件下的导航定位性能,仿真结果也验证了该算法在高动态条件下具备较好的导航定位性能。In this paper,the motion state of high dynamic target is divided into uniform motion,uniform acceleration motion and turning model.The navigation and positioning of high dynamic target is realized by estimating the current motion state of the target and then adaptively switching the motion state model among multiple models.The navigation and positioning performance of satellite navigation terminal under high dynamic condition is improved.The simulation results also verify the effectiveness of this method.The algorithm has good navigation and positioning performance under high dynamic conditions.
