Abstract

In ultrasonic equipment (anemometers and thermometers) for measurements of parameters of atmospheric turbulence usually use the standard algorithm of calculation of parameters from the temporary structural functions constructed on the registered data. Kolmogorov-Obukhov's law is the cornerstone of the algorithm. As shows experience of use of ultrasonic measuring instruments, such approach can lead to considerable errors. Therefore, a more advanced algorithm for calculating parameters is proposed, which makes it possible to more accurately estimate the structural characteristics of turbulent fluctuations with an error of not worse than 10%.
