| 高動態(tài)GPS接收機(jī)中載波環(huán)路的設(shè)計(17 卷) |
| 英文標(biāo)題 |
| Design of carrier loop of navigation receiver in high dynamic condition |
| 摘要 |
| 高動態(tài)環(huán)境在載波信號上會導(dǎo)致多普勒頻移的劇烈變化，較大的頻偏將導(dǎo)致接收機(jī)的載波環(huán)路失鎖，無法正確解調(diào)出信號。介紹一種適應(yīng)于高動態(tài)環(huán)境下的基于鎖頻鎖相環(huán)(FPLL)的載波跟蹤算法，并對其環(huán)路濾波器設(shè)計進(jìn)行詳細(xì)的分析。 |
