WIND EFFECT ON THE CHARACTERISTICS OF RADIO WAVE SCATTERING FOR THE TWO-POSITION RADIO ACOUSTIC SOUNDING
Purpose: Radio wave scattering by a sound pulse in the atmosphere when wind is present is investigated theoretically. Design/methodology/approach: The asymptotic of the scattered field in the Fresnel diffraction approximation is analyzed with Gaussian directional patterns of radiating systems....
