Abstract

Due to the prevailing impact of rain on microwave and millimetre wave propagation in tropical climates, fade margins derived from experimental campaigns would provide more practical estimates for planning. In this paper, the extent of work done on the experimental assessment of the attenuation induced by rain on practical earth-space links in Nigeria is presented. The cumulative rain rate distributions derived from the instantaneous precipitation indices for propagation modelling and the estimation of fade margin is presented for Ile-Ife, Akure, Ilorin, Ota, Osogbo and Ogbomoso. Results reveals the spatial variability of the point rainfall rate across these stations. Although the stations engaged with measurement on rain attenuation are limited in number, preliminary results from new stations are presented, while addition data from ongoing campaigns will provide a robust indices for modelling the digital DTH links and for evaluating the performance of pre-existing models over Nigeria.

尼日利亚地球-空间链路上雨水衰减测量的回顾

由于降雨对热带气候中微波和毫米波传播的普遍影响，从实验活动中得出的衰减余量将为规划提供更实际的估计。本文介绍了尼日利亚在实际地空联系上雨水引起的衰减试验评估方面所做的工作程度。利用瞬时降水指数推导了Ile-Ife、Akure、Ilorin、Ota、Osogbo和Ogbomoso的累积雨量分布，并给出了衰减边际估计。结果揭示了各站点点降雨率的空间变异性。虽然从事雨衰减测量的台站数量有限，但介绍了新台站的初步结果，而正在进行的运动的补充数据将为数字DTH链路建模和评估尼日利亚已有模型的性能提供可靠的指数。
