一种减少多径干扰的卫星信号跟踪环路设计

摘要

抗干扰技术是卫星定位导航领域中一项重要的技术，也是信号处理学科的一项重要分支。以减少卫星信号多径干扰为目的，结合多径环境下的卫星导航信号模型和卫星导航信号的跟踪捕获原理，设计出一种抗多径干扰性能较好的信号跟踪环路，该信号跟踪环路能在经典信号跟踪环路的基础上减少卫星信号的多径干扰，从而提高了整个卫星导航系统的抗干扰性能。%The anti-interference technology is is an important technology in the field of global satellite positioning and navigation system, and also is an important branch of signal processing discipline. In order to reduce multipath interference for satellite signal, and connecting with the principles of tracking and acquiring satellite navigation signal model and satellite navigation signal in multipath environment, this paper designs a signal tracking loop with better anti-multipath interference performance, which can reduce multipath interference for satellite signal based on the classic signal tracking loop, improving the anti-interference performance of the whole satellite navigation system.
