【摘要】 对多组数据进行分析后,发现散射截面的规律,以雨衰公式和M-P,J-T雨滴谱为基础,进行多组数据拟和,得出了HPM雨滴衰减截面的经验模型,利用经验模型,得出衰减率随频率和降雨量变化的规律.模型具有简单实用的特点,并且由模型所得结果、结论与有关文献完全一致.更多还原

【Abstract】 Based on multi-data analysis of the meteorological data,the characteristic of cross section is found.The model of attenuation cross section for rain drops are presented based on M-P and J-T rain drops spectrum and the formula of rain attenuation.The incoming models have the characteristic of briefness and utility.The results and conclusions obtained with the model are in good agreement with the references.更多还原
