MODE OF SOUNDING OF ATMOSPHERE OR OCEAN Russian patent published in 2005 - IPC

FIELD: the invention refers to measuring technique and may be used for sounding of atmosphere or ocean - definition of a vertical profile of a sound speed or an index of reflection.

SUBSTANCE: the technical result: simplification of realization of measuring, increasing their precision and also securing possibility of independent definition as the profile of the speed of the sound, so the profile of the index of reflection in atmosphere or in ocean. The essence: in the environment a movement of a sounding object is set up, a modulated acoustic or electromagnetic wave is directed on this object. The wave holds frequencies f₁ and f₂ and f₁≥C/h and f₂≤C/H, where C - a medium speed of the wave in the investigated environment, h - required space permission, H - a maximum distance of measuring, reradiated by the object. Corresponding relative Doppler shifts at various locations of the object are defined for frequencies f₁ and f₂ reradiated by the object. Attitude for these shifts is found. According to this attitude the vertical profile of the speed of the propagation of the wave is computed. Particularly an acoustic wave packet is chosen in quality of sounding object and a vertical profile of the speed of propagation of the electromagnetic wave is computed. The profile of the speed of the sound is defined along the profile of the shift of the frequency f₁ with taking into account the profile of the speed of propagation of the electromagnetic wave. Particularly for various moments of time an integral shift of the phase of the wave reradiated by the object on the carrier frequency is found and along this shift a slant distance till sounding object is defined. Particularly along the parameters of received signals an azimuth and an angle of the place of the sounding object are found.

EFFECT: simplification, increasing of precision, providing possibilities of independent definition of the profile of the speed of the sound and the profile of the index of reflection.
