DEVICE FOR CONTROLLING SHAPE OF REFLECTIVE SURFACE OF MIRROR-TYPE ANTENNA SYSTEM Russian patent published in 2020 - IPC H01Q3/01 G01B21/20 

FIELD: physics.

SUBSTANCE: invention relates to radio engineering, namely to antenna equipment, more specifically to devices providing obtaining information on topology and other properties of surface of object. Device for controlling the shape of the reflective surface of the mirror-type antenna system includes a reflector and receiving-transmitting antenna of scanner antenna with control system, connected through switching device with generator and receiver of radiation of radio beam, which output is connected to first input of computing device, and the first output of the computing device is connected to the input of the scanner with the control system. Device further comprises a laser diagnostic unit consisting of a laser generator, a laser receiver, a laser beam axis alignment unit and a laser beam axis alignment unit and a radio beam, wherein alignment unit of laser beam axes and radio beam is installed before switching device, wherein input/output of alignment unit of axes of laser beam and radio beam is connected to scanner antenna probe, and other input is connected to input/output of alignment unit of axes of laser beam, wherein input of alignment unit of laser beam axes is connected to output of laser generator, and the output is connected to the input of the laser receiver, the output of which is connected to the second input of the computing device, besides, the antenna of the scanner probe is made in form of combined centres of symmetry of the radio beam of the probe and the laser beam of the probe. Reflector configured as a paraboloid of revolution. Scanner antenna pattern is configured to be scanned over the cross-shaped trajectory of the reflector surface. Unit alignment axes of the laser beam and the radiation beam is formed as a radio transparent plane-parallel plate.

EFFECT: technical result when realizing the disclosed solution consists in improvement of accuracy and reliability of measurement of non-uniformity of shape of reflecting surface of mirror-type antenna system.
