Abstract: A method for operating a contactlessly operating detection device for monitoring at least one monitoring area is described. In the method, transmission signals are successively sent into at least one monitoring area. Transmitted signals which are reflected in the monitoring area are received with the detection device, brought into a form to be processed with an evaluation device, and processed as received signals. Some of the signals are allocated to at least one signal block. Information about the monitoring area is determined from some of the received signals. Some of the received signals that follow one another in time are allocated to at least one received signal block at the receiving end of the detection device, independent of any allocations of transmission signals at the transmitting end of the detection device. Some of the received signals of the received signal blocks are subjected to signal processing in blocks.

Abstract: A method for operating a radar system for a vehicle includes carrying out a radar measurement. The radar measurement includes using a transmitting antenna element of the radar system to transmit a radar signal and putting at least one receiving antenna element of the radar system on standby to receive radar echo signals based on the radar signal. The transmitting antenna element is actuated according to a control scheme. A basic control scheme for the radar system is specified according to the intended use of the radar system, and is adjusted based on a measurement node of the radar system. The basic control scheme is used to accommodate a basic main beam axis of the transmitting antenna arrangement to the intended use of the radar system.

Abstract: A method for the automated detection of a seat occupancy state, in particular related to each seat, of a seating arrangement having at least one seat comprises: receiving or generating measurement data, which represents in each case one assigned radar point cloud for each measurement frame of a sequence of a plurality of temporally consecutive measurement frames, so that the measurement data represent a sequence of radar point clouds corresponding to the sequence of measurement frames, wherein each radar point cloud of the sequence was or is obtained on the basis of a radar scan of a spatial region surrounding at least some sections of the seating arrangement, which takes place at a measurement time or during a measurement period assigned to the respective measurement frame; accumulating a plurality of the radar point clouds of the sequence in order to obtain an accumulated radar point cloud containing radar points from each of the individual radar point clouds combined as part of the accumulating process; de

Abstract: A method for determining at least one elevation variable of an object target of an object which is detected by a radar system of a vehicle, with respect to an elevation reference plane, is disclosed. The method includes emitting radar signals, receiving echo signals, determining a traveling velocity of the radar system, determining a radial velocity of an object target relative to the radar system, determining a direction variable which characterizes the direction of the object target relative to a first reference area, determining a second direction variable which characterizes the direction of the object target relative to a second reference area, and determining at least one elevation variable of the object target by means of at least one of the direction variables. Radar signals are emitted using at least one antenna of the radar system and echo signals are received using at least two antennas.

Abstract: A method and a corresponding transmitting device to encode data with a differential space-time block code. A code matrix is calculated recursively from a momentary data matrix with a previous code matrix as a DSTBC block with symbols that are to be transmitted, the data matrix is formed from at least two data symbols that are to be transmitted, and the amplitude is modulated. Amplitude modulation data is encoded into an amplitude difference of at least two data symbols within each individual DSTBC block.
