| 船载卫通站在不同海域跟踪B极化信标出现了相位渐变的现象，根据双通道接收机跟踪原理
进行公式推导，证明当和差通道极化方式不一致时，和差通道受环境和极化角影响导致的相
位变化是反向的，此时即使跟踪的是圆极化信标，极化角的变化也会导致相位变化。 |

| Abstract: |
| The phase changed in the shipboard satellite station when tracing B p
olarization signal in different waters. According to the principle of dualchan
nel rec
eiver tracking, it is known that when the sum and difference channels′ polariza
tion is inconsistent, the phase′s change caused by the environment and the pola
rization angle is in the opposite direction. At this point even if the
circular polarization signal beacon is tracked, the polarization angle′s change
will resul
t in phase′s change. |
