METHOD OF INSPECTING PARAMETERS OF AERIAL SYSTEMS Russian patent published in 2005 - IPC

FIELD: radio measurement engineering.

SUBSTANCE: method can be used for tuning and inspecting code on-board detectors of transportation vehicle automatic identification telemetric system. Section of reference aerial is calibrated in echo-free reference chamber inside which non-modulated oscillations are excited by connecting load in form of light-emitting diode cell to reference aerial. Fiber-optic section provided with light-receiving device and pre-calibrated indicator are also connected to reference aerial. Tested aerial is placed into the field induced by oscillator and measuring aerial inside working echo-free medium. The field is pre-calibrated by attenuator corresponding to readings of indicator of the reference aerial placed in the field before placing tested aerial inside the field.

EFFECT: improved truth of measurement; improved reliability of operation.
