CALIBRATION PROCEDURE FOR ACCURATE POSITIONING OF INTELLIGENT REFLECTIVE SURFACES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18296144 titled 'CALIBRATION PROCEDURE FOR ACCURATE POSITIONING OF INTELLIGENT REFLECTIVE SURFACES
The technology described in this patent application focuses on a calibration procedure for remote estimation of the position and orientation of an intelligent reflective surface. The calibration process involves accurately estimating the relative distances between each element of the reflective surface and a transmission-reception point, such as a radar sensor or a wireless access point.
- A multifrequency calibration signal is transmitted to selected elements of the intelligent reflective surface.
- The returned calibration signals are used to determine the distance to each selected element, which helps in calculating distances to other elements and the orientation of the reflective surface.
- An active backscatter tag boosts the returned signal, improving distance measurement accuracy.
- Phase delays along the path linking a target and any element of the reflective surface, as well as the path linking that element and the transmission-reception point, can be directly determined from the data obtained.
- Potential Applications:
- Radar systems - Wireless communication networks - Indoor positioning systems - Autonomous vehicles - Augmented reality applications
- Problems Solved:
- Accurate estimation of position and orientation of intelligent reflective surfaces - Improved distance measurement accuracy - Enhanced calibration procedures for remote sensing technologies

Original Abstract Submitted
The technology described herein is directed towards a calibration procedure for remote estimation of the position and orientation of an intelligent reflective surface. The calibration is based on accurate estimation of the relative distances between each element of an intelligent reflective surface and a transmission-reception point, e.g., radar sensor, wireless access point and/or base station. A multifrequency (e.g., dual-tone) calibration signal is transmitted to selected elements of the intelligent reflective surface, with the returned calibration signals used to determine the distance to each selected element, from which distances to other elements are determined, along with the intelligent reflective surface's orientation. An active backscatter tag that boosts the returned signal improves the distance measurement accuracy. From the data obtained, the phase delays along the path linking a target and any element of the intelligent reflective surface, and the path linking that element and the transmission-reception point can be directly determined.
