Orientation Estimation using Wireless Device Radiation Patterns
[article]
2022
arXiv
pre-print
Preserved Fulltext
Wireless devices inherently have a non-uniform distribution of energy from their antenna or antennas. The shape that this forms is commonly called a radiation pattern or antenna pattern. ...
We demonstrate that orientation can be estimated without the cooperation of the target device despite only having a small number of RSS measurements per packet. ...
We propose using radiation patterns to estimate the orientation of a device remotely and non-cooperatively and classify orientation values as outliers if they show unrealistic changes in orientation. ...
