根据“动中通”卫星移动通信中极化角计算的情况,分析了极化角的产生机理,并详细推导了其计算公式。在“动中通”系统实际应用中,由于载体位置不断发生改变,极化角随之改变。本文进一步推导了极化角的补偿算法,为工程应用提供了理论参考,并且已经在“动中通”系统中取得较好的应用效果。

According to the situation that the calculation of the polarization angle in the SOTM (Satcom on the move) system, the generation theory of the polarization angle was analyzed, and the calculation formula was deduced in details. The polarization angle will be changed because of the change of the position in the application of SOTM. A modified arithmetic of polarization angle was also deduced. It provides the reference of engineering application, and has been used to the SOTM system.
