摘要

由于ka波段的波长与雨滴直径非常接近，因此当ka波段信号穿过雨层时会产生较大的衰减。雨水的衰减会影响信号的传输。根据ITU-R模型的方法，对A、B、c地区Ka波段卫星通信的降雨衰减进行了估计，结果表明降雨衰减对这些地区Ka波段卫星通信的影响较大，并介绍了减少影响的措施。

Rain Attenuation Effect and Countermeasures on Ka-Band Satellite Communications

The wavelength of Ka-band is very close to the raindrop diameter, so it will cause large attenuation when the Ka-band signal through the rain layer. The rain attenuation will effect the signal transmission. According to method of ITU-R model, this paper estimates the rain attenuation of Ka-band satellite communication in region A, B and C. The result shows the rain attenuation will have great impact on Ka -band satellite communication in these areas and this paper describes the measures to reduce the impact.
