Polarimetric RCS analysis of traffic objects
Beitrag zu einer Konferenz
(Universität Ulm, 2018-01-18)
Polarimetry capable antennae, with a unique design feature, are presented which were used to perform radar cross section (RCS) measurements of traffic signs at 77 GHz. An analysis of the results in the light of near field ...
77 GHz radar-based altimeter for unmanned aerial vehicles
Beitrag zu einer Konferenz
(Universität Ulm, 2018)
For multi-copter unmanned aerial vehicles (UAVs) sensing of the actual altitude is an important task. Many functions providing increased flight safety and easy maneuverability rely on altitude data. Commonly used sensors ...

Data rate reduction for chirp-sequence based automotive radars using compressed sensing
Beitrag zu einer Konferenz
(Universität Ulm, 2018)
For autonomous driving high-resolution radar sensors are key components, which have the drawback
of high data rates. In order to reduce the amount of sampled data, random samples can be omitted
and afterwards ...
