In practice elevation direction finding arrays manifest anisotropy of directional characteristics in an azimuthal plane which is not informative and, at the same time, is subject to the account at a sizing up of an angle of elevation. The new method of direction finding of sources of radio-frequency radiation in elevation is offered a plane, based on application of the integrated operator of transformation of directional characteristics by the direction-finding aerial of the lattice, characterising it elevation directivity taking into account azimuthal anisotropy of the diagramme of directivity. Method application allows to devide out computing expenses and to raise speed scaling of an angle of elevation on a source of radio-frequency radiation.
