摘要
对于在强卫星信号的干扰下GPS接收机对弱卫星信号的捕获的性能进行了分析。对于强信号对弱信号的干扰进行了推导,讨论了几种能够改善接收机捕获性能的方法,并进行了相应的仿真,仿真的结果表明这几种方法是可行的。
The GPS receiver's acquisition performance to the weak satellite signals,that are contaminated by the strong interfering signals,is analyzed.The interference caused by the strong signals is deduced.Some methods capable of improving the acquisition performance are discussed and the simulation results prove the methods to be available.
