摘要
随着各种高速飞行器、精确打击武器的问世和应用,未来的北斗定位导航将面临更复杂更恶劣的应用环境,如高动态、强干扰等。这些都对北斗接收机的设计提出了更高的要求。本文重点研究了高动态环境下北斗接收机的部分匹配滤波与傅里叶变换相结合的快捕策略,并进行了MATLAB仿真和FPGA实现方法,证明了算法的理论正确性和实现可行性。
With the advent and application of various high speed aircrafts and precision strike weapons,Beidou navigation will face a more complex and worse application environment in the future,such as high dynamic and strong interference and so on. So higher requirements has put forward for the design of Beidou receiver. This paper focuses on the research of the fast acquisition strategy of Beidou receiver in high dynamic environment,which combine the Partial Matched Filter and Fast Fourier Transformation,carries through the simulation of MATLAB and implementation of FPGA,and prove the correctness of the algorithm theory and the feasibility of implementation.
