Abstract: A method for resolving angle ambiguities in a spatially incoherent radar network includes a surrounding area is scanned by multiple radar sensors. For each radar sensor, individually and independently of the respective other radar sensors, tracks of detected objects are generated in a state space. Tracks of different radar sensors are assigned to each other with the proviso that the tracks plausibly originate from the same object. The tracks assigned to each other are fused for different variants in order to resolve the angle ambiguities, where a respective plausibility measurement is assigned to each variant and the variant with the highest plausibility is selected in order to resolve the angle ambiguities.

Abstract: In accordance with an embodiment, a method includes: determining, based on a phase and a magnitude of complex samples of a radar receive signal, an undesired high-amplitude signal component of the radar receive signal representing an interfering motion of a target in a field of view of a radar sensor; determining a residual signal based on the undesired high-amplitude signal component and the radar receive signal; and determining a desired low-amplitude signal component of the radar receive signal representing at least one of a target motion or an electromagnetic field of the target based on the residual signal.
