本文主要讨论了南极长城站与国内短波通信的最佳方位并指出最佳方位是沿大圆路径方向;用接近对极点通信机制解释了实验结果,最后指出了在南极长城站架设南、北向天线是合理的。 This paper mainly discusses the best orientation of Antarctic Great Wall station and domestic shortwave communication and points out that the best azimuth is along the direction of the great circle path. The experimental results are explained by the near-to-pole communication mechanism. Finally, it is pointed out that erecting the south and north antennas at Antarctic Great Wall Station is reasonable.
