SPS Lecture & Networking: A Signal Processing Perspective on mmWave Radar and Temperature Profiling Probes for Snowpack and Precipitation Observations
Abstract-
This talk focuses on signal processing techniques for environmental sensing data, focusing on snowpack and precipitation monitoring using distributed temperature profiling (DTP) probes and millimeter-wave (mmWave) radar. We discuss methods for processing spatially dense temperature time series to assess snow thermal insulation, detect snow surface changes, and estimate snow depth using Fourier filtering and variability analysis. We then highlight the role of low-cost, 60 GHz FMCW mmWave radars in measuring snow depth, estimating snow density and snow water equivalent (SWE), and classifying precipitation using range-velocity analyses. The talk will also cover the development of a weatherproof, remotely operable radar system for long-term outdoor deployment. By showcasing real-time snowpack range profiles and precipitation classification, this talk highlights the intersection of signal processing, remote sensing, and environmental science, offering insights relevant to engineers and researchers working on real-time sensing systems.

Stijn Wielandt, PhD
Biography:
Dr. Wielandt is an electrical engineer and research scientist at Lawrence Berkeley National Laboratory (California), leading radio frequency (RF) research at the Earth and Environmental Sciences Area. His work focuses on low-power sensor networks and electromagnetic sensing technologies, leveraging novel communication standards and RF signal chains (e.g., mmWave radar). In 2017 he received a Ph.D. in Electrical Engineering from KU Leuven, Belgium, for his work on "Indoor Multipath Assisted Angle of Arrival Localization" using phased antenna arrays. In 2011 and 2010 he received respectively the M.Sc. and B.Sc. degrees in Engineering Technology, Electronics from the same university. Before joining LBNL in 2019, Wielandt worked as a postdoctoral researcher at KU Leuven and the UC Berkeley Wireless Research Center (California), investigating communication and localization in next-generation wireless networks.
