BEAM PATTERN AND REFLECTING SURFACE ANTENNA SYSTEM CONTROL DEVICE Russian patent published in 2020 - IPC H01Q3/01 G01R27/26 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the field of antenna equipment, namely to devices for obtaining information on the radiation pattern properties of antenna radiation when reflected from the reflector, and is intended for use in mobile radio communication systems, radar ranging from UV to THz range, as well as to study the reflecting surface of bodies and can be used in radio and radar monitoring equipment elements of detection and direction finding systems of electromagnetic radiation sources. Device for monitoring the beam pattern and shape of the reflecting surface of the antenna system includes an antenna reflector, a radar sensor of the shape of the surface of the antenna reflector, the output of which is connected to the input of the scanner with its control system, and output of scanner with its control system is connected to input of radar sensor of surface shape. Device further comprises series-connected optical antenna shape sensor of antenna reflector, which input is connected to output of scanner with control system, and integrator, second input of which is connected to output of scanner with control system, wherein the output of the integrator is connected to the first input of the antenna system distribution pattern distribution signal distribution unit, and the second input of which is connected to the antenna reflector surface radar sensor second output, wherein the second output of the radar sensor of the antenna reflector surface shape is connected to the first input of the antenna reflector surface signal release unit, and the second input of which is connected to the output of the antenna distribution pattern allocation unit of the antenna system.

EFFECT: high accuracy and reliability of separate measurement of non-uniformity of the beam pattern of the radiator of the radar sensor and the shape of the reflecting surface of the antenna system.
