中文摘要：

主要介绍了一种在GNSS信号中抑制多径信号的鉴相方法，接收机接收到的GNSS信号中往往包含多径信号，GNSS信号进行下变频生成中频信号后，进行模数转换；将经过模数转换后的GNSS信号进行载波剥离，得到I路和Q路的信号，在码跟踪环路中，对I路和Q路信号进行码剥离，得到多径信号的互相关功率后，采用基于精密TK采样间隔的TK—EML5鉴相方法，能够起到有效地抑制多径信号的效果。

英文摘要：

A discriminate method which can restrain multipath signals in the GNSS is de- scribed. The received GNSS signals often contain multipath signals. After down-conversion to the IF signal, analog GNSS signals are converted to digital signals. Then After stripping the carrier signals, the digital GNSS signals can be disposed to receive channel I and channel Q signals. After code stripping the I and Q signals, the corss-correlation power of the mul- tipath signals can be received in the code tracking loop. TK-EML5 multipath signals based on the precision TK sampling interval is taken, and it can make effectives in inhibit the mul- tipath signals.
