Paper Abstract

It is well known that the directivity patterns of the radio wave scattering by temperature and humidity fluctuations and by the cross correlation of temperature and humidity fluctuations are the same. On the other hand, it has recently been revealed that for a sound wave these directivity patterns as well as the directivity pattern of sound scattering by wind velocity fluctuations are different. This fact allows us to propose new methods for simultaneous measuring the structure parameters for temperature, temperature-humidity, humidity and wind velocity fluctuations. For example, measuring the radio wave backscattering cross section by a clear air radar, and measuring the sound scattering cross section by monostatic and bistatic acoustic sounding at three different scattering angles, we may in principle retrieve these structure parameters. Note that now there is no good remote sensing method for measuring the structure parameters for humidity and temperature-humidity fluctuations in the atmosphere. Some problems of practical realization of the proposed methods are considered.
