  • Patent number: 11415695
    Abstract: A Distance Measuring (DM)-system comprising a DM-device comprising a measuring beam unit configured for determining a distance between an object and the DM-device by transmitting a measuring beam, and an Inertial Measurement Unit (IMU) configured for determining an absolute first rotational position of the DM-device with respect to a first axis being parallel to the measuring beam, and an absolute second rotational position of the DM-device with respect to a second axis parallel to the gravity field. The DM-system also includes a computer unit configured for receiving from the DM-device a plurality of measured distance values, an absolute first rotational position of the DM-device at the time of a respective distance measurement, and an absolute second rotational position of the DM-device at the time of a respective distance measurement, and generating a layout by consecutively linking the measured distances based on the plurality of measured distance values.

  • Publication number: 20220252697
    Abstract: 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.
