A method for providing personal tracking data for controlling at least one function of a technical system. The method includes reading in, executing, and generating. During the reading in, sensor data from two spaced-apart radar sensors with partially overlapping fields of view are read in, the sensor data representing a point cloud made up of point targets that are detected with the aid of the radar sensors. During the execution, an estimation algorithm is executed, using the sensor data, in order to generate at least one corrected position profile track, the estimation algorithm applying a density-based cluster analysis algorithm. During the generating, the tracking data are generated using the at least one corrected position profile track.

An OFDM radar sensor system having a plurality of transmitting and receiving units. One of the transmitting and receiving units is an OFDM radar sensor, and another of the transmitting and receiving units is a repeater which is configured to modulate a signal generated and transmitted by the OFDM radar sensor and received by the repeater into a signal orthogonal to the signal received by the repeater and to emit the modulated signal. The OFDM radar sensor is configured to separate a portion of a signal received by the OFDM radar sensor, which portion corresponds to the modulated signal, from a monostatic portion of the signal received by the OFDM radar sensor.

An OFDM radar sensor including multiple transmission channels and at least one reception channel, and a method for operating such an OFDM radar sensor. At least for first transmission channels, the signal form of the signal to be transmitted, which includes a sequence of OFDM symbols in question, is progressively computed in portions for each transmission channel, and multiple buffer memories are used in alternation for storing a computed portion of the signal form and for reading out a previously computed and stored preceding portion of the signal form, which is converted from digital to analog and transmitted. A particular portion of the signal form is computed and stored in one of the buffer memories while a preceding portion of the signal form is being read out from another of the buffer memories and converted from digital to analog, and transmitted on the transmission channel in question.

A method for generating synthetic measurement data indistinguishable from actual measurement data captured by a first physical measurement modality. The first physical measurement modality is based on emitting an interrogating wave towards an object and recording a reflected wave coming from the object in a manner that allows for a determination of the time-of-flight between the emission of the interrogating beam and the arrival of the reflected wave. The method includes: obtaining a first compressed representation of the synthetic measurement data in a first latent space, wherein this first latent space is associated with a first decoder that is trained to map each element of the first latent space to a record of synthetic measurement data that is indistinguishable from records of actual measurement data of the first physical measurement modality, and applying the first decoder to the first compressed representation, so as to obtain the sought synthetic measurement data.
