The invention discloses a radio wave propagation-based atmospheric parameter data complete fitting method. The radio wave propagation-based atmospheric parameter data complete fitting method comprises the steps of analyzing atmospheric parameters through numerical calculation, iterative check, linear fitting and statistic methods to obtain change situations of temperature, atmospheric pressure intensity and relative humidity under different heights; performing complementation on missing data to generate continuous data under different heights; and performing assessment on a data complementation method. According to the method, the missing data is complemented through a relationship among the height, the pressure intensity, the temperature, the temperature dew-point spread and the relative humidity; missing pressure intensity value and height value can be obtained through obtained curve and expression of the pressure intensity changed with the height and are complemented; missing temperature data is obtained by utilizing obtained curve and expression of the temperature changed with the height; and the dew-point temperature is calculated by utilizing the relationship among the relative humidity, the temperature and the dew-point temperature, and data of the temperature dew-point spread is complemented.
Description
technical field [0001] The invention belongs to the technical field of radio wave transmission, in particular to a method for complete fitting of atmospheric parameter data based on radio wave propagation. Background technique [0002] Radio wave transmission is the basis of electronic communication technology, and the atmospheric transmission attenuation value of electromagnetic waves is an important parameter to realize radio wave transmission. The transmission loss of electromagnetic waves is closely related to atmospheric parameters, such as temperature, atmospheric pressure, relative humidity and other related data. Although these data cannot be directly used to calculate the atmospheric attenuation of electromagnetic waves, the required data can be obtained through conversion and calculation of these data, and then the atmospheric attenuation of terahertz waves can be calculated. Obtain complete upper-altitude atmospheric parameter values according to requirements, ...
