Snow noise disturbance in Antarctic radio communications and development of mobile antenna for snow vehicle in Antarctica
Radio operators of the Japanese Antarctic Research Expedition (JARE) have encountered critical radio noise disturbances caused by blizzards during oversnow travel. This noise appears to be caused by corona discharge at the edges of the vertical whip antenna. This paper describes several examples of...

| Summary: | Radio operators of the Japanese Antarctic Research Expedition (JARE) have encountered critical radio noise disturbances caused by blizzards during oversnow travel. This noise appears to be caused by corona discharge at the edges of the vertical whip antenna. This paper describes several examples of snow noise experienced in Antarctica by JARE, the mechanism of generation of the noise, and a method of reducing the intensity of the noise. It also describes a High Effeciency Transmission Line Antenna which is small enough to mount on a snow vehicle and reduces the intensity of the snow noise. |
