  In this work a novel radar simulation concept is introduced that allows to
simulate realistic radar data for Range, Doppler, and for arbitrary antenna
positions in an efficient way. Further, it makes it possible to automatically
annotate the simulated radar signal by allowing to decompose it into different
parts. This approach allows not only almost perfect annotations possible, but
also allows the annotation of exotic effects, such as multi-path effects or to
label signal parts originating from different parts of an object. This is
possible by adapting the computation process of a Monte Carlo shooting and
bouncing rays (SBR) simulator. By considering the hits of each simulated ray,
various meta data can be stored such as hit position, mesh pointer, object IDs,
and many more. This collected meta data can then be utilized to predict the
change of path lengths introduced by object motion to obtain Doppler
information or to apply specific ray filter rules in order obtain radar signals
that only fulfil specific conditions, such as multiple bounces or containing
specific object IDs. Using this approach, perfect and otherwise almost
impossible annotations schemes can be realized.
