METHOD FOR DETERMINING INTERVALS OF RELATIVE STATIONARITY OF SIGNALS OF IONOSPHERE-SPATIAL PROPAGATION OF RADIO WAVES Russian patent published in 2020 - IPC G01S13/00 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, specifically to a method for real-time determination of current intervals of relative stationarity of signals of over-the-horizon radar. Current stationarity intervals are measured by cyclic scanning of location trajectories by back-inclined probing (BIP) δ_D-probing with period T_δi, set by cycles generator. Then, two "test" ones, displayed by Dirac functions, are emitted in turn at the working frequency, signal - quasi-monochromatic "switching" and strobe-pulse. Then, radio reception, commutation of received test signals , signals is performed . Further stationarity of test signals is evaluated and processed with allowance for local delay.

EFFECT: invention is intended to provide adaptation of systems of over-the-horizon radar by method of real-time measurements of current intervals of stationarity of ionospheric-spatial propagation of radio waves.
