Accurate and reliable determination of the vehicle's location is a key requirement for autonomous driving. We tackle localization using mono-static radar in addition to radio signal measurements to base station as well as cooperative vehicles. At this page you may find our published papers and, if possible, the implementation to generate the corresponding results. Feel free to contact us!
Conventional localization systems rely on measurements to numerous base stations with known position. In these works we show that multipath propagation offers position information which circumvents the need for base stations. Long story short, localization using absolute coordinates without any base station.

Cooperative Multipath-assisted Navigation and Tracking: A Low-Complexity Approach
1st EAI International Conference on Future access enablers of ubiquitous and intelligent infrastructures, 2015
We were interested to what extend a single measurement to a single base station suffices to get an position accuracy in levels of centimeters. The answer is simple, (1) temporal resolution and (2) spatial resolution in order to separate the signal reflections. We derived a low-complexity algorithm able to perform real-time positioning on a commercial available platform. Only a single base station is requried.
