Project content Terrestrial microwave interferometry (MI) is a rather new measuring method that offers the possibility of contact-free determination of deformations of entire structures with an accuracy of submillimetre degree at a sampling rate of up to 4000 Hz and a high three-dimensional resolution.
The main objectives of the STRAMIK project are testing the new MI technology for railroad specific applications for monitoring and technical analysis of infrastructural elements such as bridges and noise-walls, proof of usability of measured data for Deutsche Bahn projects, and subsequently the development of a concept for holistic MI measuring methodology optimized for railroad specific applications as well as working out loadbearing design requirements and boundary conditions for use in the MI measuring technique.
