摘要
The invention relates to methods for radar metrology for measurement of parameters of atmosphere. Method for determination of type of temperature stratification of atmosphere includes measurement of coefficient of anisotropy (K) of temperature heterogeneities of atmosphere, determination of type of temperature stratification of atmosphere on basis of measured coefficient of anisotropy and obtained before dependence of coefficient of anisotropy () on type of temperature stratification of atmosphere. Coefficient of anisotropy is measured for chaotic rate of molecules () through measuring anisotropic phase of acoustic echo-signal () in vertical plane that is relates to chaotic velocity of molecules by reverse dependence, at pulse mono-static acoustic probing atmosphere in vertical plane, simultaneously in two or more different at angle of elevation () directions, at that to increase range of measured temperature stratification of atmosphere one performs multiplication of frequency of echo-signal detected by value n, with dividing frequency of echos0gnal detected by value n, at that selection of value n is determined under condition for which one determines temperature stratification and coefficient of anisotropy of phase of acoustic echo-signal () one determines on basis dependence of phase of acoustic echo-signal () on angle of elevation (), obtained, as difference of values and , at that value of phase for horizontal direction determined at extrapolation of dependence = f() for angles = 0°, and value of phase for vertical direction obtained for angles = 90°, after that for coefficient of anisotropy of phase of acoustic echo-signal obtained in such way, = -on basis pf obtained before experimentally dependence of coefficient of anisotropy of phase of acoustic echo-signal K on type of temperature stratification of atmosphere one determines type of temperature stratification of atmosphere. The invention provides increase of accuracy of remote measurement or type of temperature stratification of atmosphere.
