Abstract: A method for the use in a radar system comprises: receiving an RF radar signal; down-converting the received RF radar signal into a base band using a frequency-modulated local oscillator signal including a scanning chirp having a higher bandwidth than a regular chirp bandwidth; generating a digital base band signal based on the down-converted RF radar signal, the digital base band signal including a sequence of samples associated with the scanning chirp; identifying, in the sequence of samples, impaired samples, which are affected by interference; and selecting—based on the position of the impaired samples within the sequence of samples—a sub-band, which has the regular chirp bandwidth, for transmitting chirps of chirp frame used for measurement data acquisition.

Abstract: A radar sensor is described herein. In accordance with one example embodiment the radar sensor includes a transmitter for transmitting an RF signal and a receiver configured to receive a respective back-scattered signal from at least one radar target and to provide a corresponding digital radar signal. The radar sensor further includes a processor configured to convert the digital radar signal into the frequency do-main thus providing respective frequency domain data and to compress the frequency domain data. A communication interface is configured to transmit the compressed frequency domain data via a communication link operably coupled to the communication interface. Furthermore, respective and related radar methods and systems are described.

Abstract: The present disclosure relates to a concept for detecting radar targets. A plurality of first receive signals is received from first antennas of an antenna array. A first combined range-Doppler map is determined by combining range-Doppler maps of each of the first antennas. First confirmable range-Doppler cells of the first combined range-Doppler map are determined which match a predetermined confirmation criterion. A plurality of second receive signals is received from second antennas of the antenna array. A second combined range-Doppler map is determined by combining range-Doppler maps of each of the second antennas. Second confirmable range-Doppler cells of the second combined range-Doppler map are determined which match the predetermined confirmation criterion. The first and second confirmable range-Doppler cells are combined to obtain a set of confirmable range-Doppler cells. Values of the first and the second combined range-Doppler maps corresponding to the set of confirmable range-Doppler cells are summed to obtain summed values of the combined confirmable range-Doppler cells. Summed values of the total confirmable range-Doppler cells exceeding a predefined selection threshold are selected for target detection.
