摘要
捕获能够帮助接收机初始化跟踪环路并开始跟踪信号,捕获的好坏对定位有较大影响。文中对L1频段的GPS信号进行定位研究,分别研究了传统的串行搜索卫星捕获过程,讨论了基于分段FFT的脉冲信号捕获算法。仿真结果表明,基于分段FFT的脉冲信号捕获算法在高信噪比时效果更好。
The capture of the signal helps the receiver to initialize the tracking loop and start tracking of the sig- nal. This paper discusses the localization of GPS signals of L1 band by the traditional serial search satellite acquisi- tion process and by the subsection - FFT - based pulse signal acquisition algorithm, respectively. The simulation re- suits show that the subsection - FFT - based pulse signal acquisition algorithm has better performance with a high sig- nal - to - noise ratio.
