Abstract (en)

[origin: WO2014161687A1] The present invention creates a modulation concept for a radar having switched antennas. Individual switching states of the antenna array having the switched antennas are tightly intermeshed with the modulation of the radar signals. In this manner it is possible to use switched antennas in the time-multiplex method and thus enable short times between the switching states. This enables a phase evaluation even across the switching states.
