Abstract:
1. A radar system, comprising: at least two spatially separated antenna units, wherein each antenna unit has one antenna, wherein at least two of the antenna units each has a signal generator coupled to an antenna so as to constitute transmitting antenna units and wherein at least one of the antenna units has a receiver coupled to an antenna so as to constitute at least one receiving antenna unit, the receiving antenna unit being arranged for receiving at least one reflected signal, being signals generated by said signal generators and transmitted by the transmitting antenna units, having been reflected from at least one object; a processing unit; a means for coupling the transmitting antenna units and the receiving antenna unit to the processing unit; the processing unit being arranged to perform a correlation calculation, comparing at least one received signal, fed from said receiving antenna unit with a set of superimposed combinations of delayed and contracted or elongated copies of the signals generated by said signal generators, where only one certain combination corresponds to said reflected signal, the processing unit being further arranged to calculate said set of combinations with the signals generated by said signal generators as input, and where information about said object is calculated using said corresponding combination for each reflected signal.
