THE ANTENNA LATTICE ACTIVE PHASE DIAGNOSTIC METHOD Russian patent published in 2017 - IPC H01Q21/00 

FIELD: radio engineering, communication.

SUBSTANCE: while solving the problem diagnostic, use the current complex amplitude (or voltage) data of the radiators excitation and measurement data obtained in the same SE locations, while radiating the signals of defectless bearing headlamp, located at testing headlamp place and structurally completely coincides with it. Then form the difference function of complex excitation amplitudes of new rarefied headlamps radiators and the difference function of complex voltages, registered at the probe outlet at the points of provided measurements. In the prototype model on the basis of the new rarefied headlamps characteristics awareness of the further formation and minimization of the target function, determine with acceptable probability, depending on the level of measurements errors and the additive noise, the coordinates of all radiators of tested headlamp, the number of potentially defective (PD) radiators, that can be included in the group of working or defective radiators. The proposed diagnostic method allows on the basis of additional measurements by the stationary probe to determine the phase of any of the PD radiators of the headlamp, being tested by changing its excitation phase at 180°.

EFFECT: increase of the reliability, increase of the accuracy and creation of new functionalities in diagnostics of the tested headlamps in comparison with the prototype model, realized on the basis of phase failure error determination or the phase control device complete failure in any PD or defective radiators of the headlamps being tested, creating the effective classification criterion of the tested headlamps PD radiators for working and obviously defective.
