微波动态雨衰减时间序列模型的修正
Improvement on the microwave dynamic rain attenuation time series model
摘要
Abstract
In ordor to investigate the dynamic rain attenuation forecast in countermeasure rain fade techniques on the microwave link , in typical temperate and subtropical rain areas in China , the power spectra for the rain attenuation time series simulated by the EMB ( Enhanced Maseng and Bakken) model are in agreement with the measured results at 12.5 GHz , but there are differences between the fade slopes statistics based on simulated series and measured data . The rain attenuation time series by the EMB model are improved by using a circular inserting data method . By the improved method , the statistical probabilities of the fade slopes are very close approximation to the measured results . The probabilities of the fade duration based on the simulated time series by the improved processes are compared with the results by unimproved processes , the results based on the measured data and by the ITU -R predicted results . It is shown that the statistical results for the fade slopes are improved , and that the differences between the fade duration probabilities by the improved series and measured data are smaller than that between the results by unimproved and measured . The results show that the improved process to the EMB model is feasible in typical rain areas in China .关键词
