AI Technical Summary
Technical Problem
Existing radars have a fixed scanning range for their emitted beams, making it difficult to adjust them according to the size of the detection range required, thus limiting the application scope of radars.
Method used
By setting up high-level driving structures and low-level driving structures in the reflective unit structure, the refractive index of the liquid crystal material is controlled by forming an electric field, thereby adjusting the scanning range of the radar beam.
Benefits of technology
By adjusting the refractive index of the liquid crystal material, the reflection angle of the radar beam can be controlled, thus expanding the application range of radar and its scanning angle adjustment capability.

Abstract
This application discloses a reflective unit structure, device, control method, and related equipment, relating to the field of detection technology. It can control and adjust the scanning range of a radar beam, expanding the application range of radar. The reflective unit structure includes: a material cavity containing liquid crystal material; a low-level driving structure; and a high-level driving structure, with different high-level driving structures being mutually insulated. Both the high-level and low-level driving structures are disposed on the outer wall surface of the material cavity, and the electric field formed by the high-level and low-level driving structures passes through at least a portion of the liquid crystal material.
