Abstract: A method for processing radar signals includes emitting a first radar signal via a transmitting antenna of a first radar unit, where the first radar signal is phase modulated using a first code and a first frequency offset is added to at least a portion of the first radar signal, and emitting a second radar signal via a transmitting antenna of a second radar unit, where the second radar signal is phase modulated using a second code. The first code and the second code are orthogonal to each other and the first radar unit and the second radar unit are loosely coupled with each other.
