摘要： The present disclosure generally relates to a multistatic radar system and a method for a spatially resolved detection of an object under test. The multistatic radar system includes an at least two-dimensional multistatic array of antenna elements having an at least partially shared coverage area. At least one data processing circuit is coupled to the array. Analog and/or digital beamforming is performed thereby obtaining at least one image of the object under test at least partially being located within the shared coverage area. Processing the image obtained is used to resolve at least one scattering center of the object under test. A spatially resolved scattering center distribution is determined based on the image obtained.

摘要： A permittivity sensor, for determining an image of a distribution of permittivity of a material of an object in a scene, comprising an input interface, a hardware processor, and an output interface is provided. The input interface is configured to accept phaseless measurements of propagation of a known incident field through the scene and scattered by the material of the object in the scene. The hardware processor is configured to solve a multi-variable minimization problem over unknown phases of the phaseless measurements and unknown image of the permittivity of the material of the object by minimizing a difference of a nonlinear function of the known incident field and the unknown image with a product of known magnitudes of the phaseless measurements and the unknown phases. Further, the output interface is configured to render the permittivity of the material of the object provided by the solution of the multi-variable minimization problem.

摘要： In a method and system for position capture of a vehicle along a driving route, situated on a concrete floor having a reinforcement: the vehicle carries out a reference drive along the driving route, the vehicle records measuring points along the driving route, and each measuring point allocates a signal from the reinforcement to a position on the driving route; a reference profile of the driving route is determined based on the measuring points ascertained during the reference drive; the vehicle drives along the driving route and records further measuring points; a profile segment is determined from the further measuring points; the profile segment is uniquely allocated to a segment of the reference profile, e.g., using a correlation method; a position on the driving route is uniquely allocated to the vehicle with the aid of the profile segment allocated to the reference profile.

摘要： The present disclosure relates to a system for generating a digital map of an environment. The system comprises at least one sensor which is configured to record sensor data and a position of an object within the environment together with a time-stamp of recording the sensor data. Further, the system comprises a data processing circuitry configured to determine a time-dependent presence probability distribution of the object based on the sensor data. The presence probability distribution is indicative of a probability of the object being at its position before, after and/or at a time of the time-stamp. The data processing circuitry is further configured to register the presence probability distribution of the object in the digital map of an environment of the object.

摘要： An evaluation system for processing measured data which include physical measured data detected with the aid of one or multiple sensors, and/or realistic synthetic measured data of the sensor(s), into one or multiple evaluation results. The system includes at least two input stages independent from each other, which are designed to receive measured data and process these measured data into precursors. At least one processing stage, receives the precursors from all input stages as inputs and is designed to process one or multiple input precursor(s) into a shared intermediate product. At least one output stage, which is designed to process the intermediate product into one or multiple evaluation result(s) of the evaluation system. A method for training the evaluation system. A method for operating the evaluation system is also provided.

摘要： A method for monitoring a sensor system. Sensor data of the sensor system are read in and information of the sensor data from different elevations of the sensor data is projected as image data into an azimuthal image plane. The information from at least two image areas of the image plane is evaluated in a spatially resolved manner in order to recognize a local sensor blindness of the sensor system. A blindness notification for an image area is output if the sensor blindness is recognized in the image area.

摘要： A method may include capturing image data associated with an object in a defined environment at one or more points in time. The method may include capturing radar data associated with the object in the defined environment at the same points in time. The method may include obtaining, by a machine learning model, the image data and the radar data associated with the object in the defined environment. The method may include pairing each image datum with a corresponding radar datum based on a chronological occurrence of the image data and the radar data. The method may include generating, by the machine learning model, a three-dimensional motion representation associated with the object that is associated with the image data and the radar data.

摘要： A method includes generating emitted signals using transmitter elements and measuring received signals using receiver elements. The received signals are reflected portions of the emitted signals and the received signals correspond to one or more targets. The method also includes applying a first matched filter to the received signals to determine range information for the received signals, filtering the received signals based on the range information to define filtered signals, and determining calibration parameters using the filtered signals. The method also includes correcting the received signals using the calibration parameters to define calibrated signals and determining angle of arrival information for the received signals using the calibrated signals.
