中文摘要：

高动态意味着载波多普勒频移变化率较大，实际中真实的高动态信号通常难以采集到，比如在弹载、星载环境下。为了研究高动态GPS信号跟踪问题，首先设计了一种高动态GPS中频数字信号仿真模型，并在此基础上研究了一种基于Kalman滤波理论的高动态信号跟踪技术。信号的模拟和跟踪都是基于Matlab的Simulink环境，仿真结果显示高动态信号模拟理想，应用Kalman滤波理论的高动态跟踪技术跟踪稳定，精度满足要求。

英文摘要：

High dynamics implys high change rate of carrier Doppler. However the GPS signal is difficult to collect in fact, such as in missile-borne and satellite-borne environments. The simulation model of the high dynamic GPS signal was designed and tracking method based on Kalman filtering theory was simulated for the purpose of GPS signal tracking research in the high dynamic environments. The signal simulation and tracking were completed with the Matlab Simulink tool. The simulation results reveal that the signal simulation is perfect, and the tracking based Kalman algorithm is steady and with satisfactory performance.
