METHOD FOR EARLY DETECTION OF ATMOSPHERIC VORTICES IN CLOUDS USING NONCOHERENT RADAR Russian patent published in 2013 - IPC G01S13/95 

FIELD: radio engineering, communication.

SUBSTANCE: detection of cyclonic vortices in thunder clouds using noncoherent radar involves radar probing of the cloud at wavelength of 10 cm, determining reflectivity at given spatial points of the cloud environment, and displaying said data on the screen of a personal computer in form of a three-dimensional radar image of the cloud; the obtained image of the cloud is viewed from all sides on the background of the screen of the personal computer in dynamic mode, removing, during each view of the three-dimensional image, the external envelope which corresponds to a 2 dBZ drop in radar reflectivity; upon detecting a contour of the presumed cavity of the atmospheric vortex on the surface of the image, the image is viewed on the background of the screen of the personal computer and if the colour of the detected cavity matches that of the background of the screen of the personal computer, said cavity is identified as the cavity of the atmospheric vortex.

EFFECT: high information value and accuracy of early detection of atmospheric vortices.
