A radar system comprising at least two spatially separated antenna units, each comprising one antenna. Each antenna unit comprising a signal generator connected to an antenna constitutes a transmitting antenna unit, and each antenna comprising a receiver connected to an antenna constitutes a receiving antenna. At least one receiving antenna unit is arranged for receiving at least one reflected signal, comprising signals transmitted from at least one transmitting antenna unit, having been reflected from at least one object, where the number of antenna units exceeds two. A processing unit is arranged to perform a correlation calculation, comparing at least one received signal with a set of mathematically manipulated copies. From said set, there is only one match for each reflected signal. The present invention also relates to corresponding methods.
