I was invited to report about our recent radar-based wind energy activities in the DGZfP expert committee Structural Health Monitoring. The presentation was divided into three sections: Grout-Radar, Tower-Radar and In-Blade Radar. A big thanks goes out to my working group, the numerous cooperation partners, and the funding agencies. Reference Grout-Radar: Maetz, T.; Kappel, J.;...Read More

The following article on explainable machine learning under the leadership of Sercan Alipek has been accepted for publication in Sensors journal. Abstract: This paper evaluates a data-driven classification approach of operational wind turbine blades based on consecutive tower-radar measurements that are each compressed in a two-dimensional slow-time to range representation (radargram). Like many real-world machine...Read More

A journal article demonstrating recent developments on a reversible damage model for the qualification of radar-based SHM systems has been accepted for publication in PIER C. Abstract: In this work, a delamination model for millimeter-wave inspections of glass fiber reinforced polymer (GFRP) is proposed that replicates the scattering characteristics of a real delamination. The model...Read More

A joint work of researchers from different countries (Spain, Italy, Germany) has been accepted for publication in Applied Sciences. Abstract: This paper introduces a novel structural health monitoring (SHM) approach based on guided electromagnetic waves propagating in a dielectric waveguide in the frequency range from 23.5 to 26 GHz. This approach enables the detection of...Read More
