摘要： Estimating the ego-motion of a vehicle, e.g., the self-motion of the vehicle, can be improved by pre-processing data from two or more radars onboard the vehicle using a processor common to the two or more radars. The common processor can pre-process the data using a velocity vector processing technique that can estimate a velocity vector at each point of a predefined number of points, such as arranged in a grid in the field-of-view of radars, with coordinates (X, Y, Z (optional)), where U is the component of the velocity in the X-direction, V is the component of the velocity in the Y-direction, and W is the component of the velocity in the optional Z-direction.

摘要： 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. At least one spatial sub-field of the field of vision (FoV) is constructed using the determined vector velocity ({right arrow over (v)}) and/or the vector velocity ({right arrow over (v)}100) for the radar system and with the measurement data of at least one of the radar units (10, 20).
