New Publication in IEEE Journal of Microwaves
We are thrilled to announce that EmpkinS doctoral candidate Johanna Bräunig has published a groundbreaking paper titled „A Radar-Based Concept for Simultaneous High-Resolution Imaging and Pixel-Wise Velocity Analysis for Tracking Human Motion“ in IEEE Journal of Microwaves.
About the Publication
In this paper, Johanna Bräunig and her co-authors introduce an exciting new motion tracking concept that greatly improves on the accuracy and resolution of existing Doppler and range methods. They utilize a near-field back projection technique that displays successive images and compares phase changes on a pixel-by-pixel comparison. They first derive the new method and then demonstrate its efficacy by tracking human hand motions with a radial position accuracy of better than 1.5mm (mean absolute error). The instrument they use for their demonstration is based on an 80 GHz MIMO radar system with 94 Tx and 94 Rx modules arranged in two perpendicular lines and used in the near field. Range processing algorithms have to be significantly modified in the near field regime and so far, the method only attempts to track axial motion. However, the technique described is foundational and may be applied to the more general problem of tracking precise motion and speed in both axial and lateral coordinates and over large surfaces requiring significant angular span and high angular resolution.
