Analysis of the influence of a solenoid magnetic field in the azimuth transmission system

Abstract A solenoid magnetic field plays an important role in a non-line-of-sight azimuth transmission system based on polarization-maintaining fiber, which is directly related to the transmission accuracy of azimuth information. This research mainly studies the factors that affect the solenoid magn...
