الوصف: We present the theory of radio-acoustic sounding (RAS) of the atmosphere allowing for the dependence on temperature, altitude, and wind. For the case of a linear temperature profile, we obtained expressions for the received signal power. Since the acoustic wave front differs from the sphere if the temperature gradient is allowed for, we can introduce the notion of projector (Fresnel) and Fraunhofer regions. In the Fresnel region, the size of the diffraction spot on the earth is determined by radar antenna dimensions and the received signal power is proportional to z−2. In the Fraunhofer region, the spot size is greater than the antenna dimensions and the power is proportional to z−6. The existing RAS facilities work in the projector region. This can be used as a basis for developing a new method of diagnostics of a large-scale inhomogeneous atmospheric structure, including wave disturbances.
