Abstract: A method for signal processing of radar signals of a radar system (100) has at least two radar units (10, 20) arranged at a known distance from one another. At least one spatial field of vision (FoV) of the radar system (100) is captured with radar signals of the at least two radar units (10, 20). A discrete total coordinate system is generated from the field of vision (FoV). Measurement data of the at least two radar units (10, 20) of the radar system (100) generated by the detection of the field of vision (FoV) are co-registered. A multidimensional, vector velocity ({right arrow over (v)}) for at least one resolution cell of the discrete total coordinate system and/or a multidimensional, vector velocity ({right arrow over (v)}100) for the radar system (100) are generated.

Abstract: A method and related system are provided for locating a current position or a coupling location of a mobile unit, which can send or receive for location determining purposes, using a leaky waveguide, wherein a radio signal is fed from the mobile unit into the waveguide or vice versa, wherein the signal is sent by the mobile unit and received by the two transmitting and receiving (T/R) apparatuses, or one signal is sent by each of the two T/R apparatuses and received by the mobile unit, wherein a receiving time is determined for each received signal, and the current position or the coupling location is determined from two such receiving times. The T/R apparatuses, arranged at opposite ends of the waveguide, are synchronized relative to each other prior to the determination of the current position or coupling location, or prior to the reception of the signal.
