Granular matter is an agglomeration of macroscopic particles, which offers the opportunity to trace its dynamical behavior down to the mobility of individual particles. However, particle tracking in three dimensions, especially in an opaque medium such as a densely packed granular pile, is far from trivial. Here we introduce a microwave radar setup designed to trace a metallic particle in real time. The method is based on the phase shift between transmitted and reflected microwave signals, which are recorded by means of three receiver antennas. The tracing algorithms and first experiments to calibrate the setup will be presented.
