METHOD OF FORMING A WIDE-SCALE ZONE SCAN OF THE ANTENNA SYSTEM WITH ELECTRON BEAM CONTROL Russian patent published in 2018 - IPC H01Q21/00 

FIELD: radar ranging and radio navigation.

SUBSTANCE: method is based on the changing the phase distribution in the antenna system aperture with the electron beam-control (AC with EBC) by electronically controlling the phase shift of the microwave signal in each of its emitters and forming an electronic scanning zone with solid angle equal to ±θ, where θ – angle of the beam deflection of AC with EBC from the normal to its aperture, the arrangement of the AC with EBC on the rotary device, which ensures its rotation about its axis by angle β, which varies from 0° up to 360°, the summation of electronic and mechanical scanning zones. AC with EBC is installed to a two-coordinate rotary device having independent external and internal turning nodes, in such a way, that the normal to its aperture coincides with the axis of rotation of the external node of the two-coordinate rotary device, that ensures its rotation through angle β, varying from 0 to 360°, where β – angle of rotation of the AC with EBC relative to the axis of rotation of the external rotation unit of the two-coordinate rotary device, the inner corner of rotation of the two-axis rotary device is changed by angle α between the axis of rotation of the external knot of rotation of the two-coordinate rotary device and the normal to the aperture of the AC with EBC to values ±α. It is carried out the rotation of the AC with EBC aperture by an external rotation unit of a two-axis rotary device, changing angle β. Produce a change in the phase distribution in the AC with EBC aperture taking into account angles α and β, carrying out an electron beam scan in the AC with EBC scanning zone, but with respect to this position of the normal to AC with EBC aperture. By independent rotating of the AC with EBC around the rotation axes of the inner and outer knots of the rotation of the two-coordinate rotary device within limits of α before ±α and on β from 0° up to 360° move the normal to AC with EBC aperture in an arbitrary direction inside a conical solid angle of size ±α, thereby forming a zone of mechanical movement of the normal to the aperture of AC with EBC.

EFFECT: technical result consists in expanding the scanning zone.
