RADAR DEVICE FOR CLASSIFYING VIBRATING AIRCRAFT WITH FLIGHT PATH INSTABILITIES IN SURFACE LAYERS Russian patent published in 2010 - IPC G01S7/41 

FIELD: physics.

SUBSTANCE: disclosed device has a synchroniser, a modulator, a microwave oscillator, an antenna switch, a receiver, a range measuring system, a resolver, an antenna, an antenna control system, a velocity measuring system, three analogue-to-digital converters, memory, a fast Fourier transformation computer, a classification unit, designed and connected to each other in a certain way.

EFFECT: high quality of classifying location objects according to the structure of a vibration map owing to further consideration of phase information of reflected signals, owing to exclusion of components arising from direct reflection from the body of an object and presence of scanning frequencies, and owing to averaging of negative spectral components of the turbo-prop effect.
