Zusammenfassung: | A stationary radar device, which apart from a plurality of stationary receiving antennae, includes a plurality of stationary transmitting antennae for emitting primary radio waves. A frequency-modulated emitting signal is generated in two sequences. During the first sequences a plurality of successive first chirps are emitted by one of the transmitting antennae. A Doppler shift or a speed is computed from the temporal development of the respective first receiving signals. The second sequences are intermitted with the first sequences and each include one or more second chirps, wherein the second chirps are produced from different transmitting antennae. The second receiving signals which are effected by the second chirps are evaluated, in order by way of correlation of receiving signals that originate from second chips, which come from different transmitting antennae, to obtain a phase picture that is resolved in the azimuth. |
