Abstract: It is suggested to process radar signals at a first radar unit as follows: (i) receiving the radar signals via at least one receiving antenna; (ii) selecting a portion of the radar signals or of data that is based on the radar signals for further processing; and (iii) conveying a reduced amount of data to a second radar unit, wherein the reduced amount of data is based on the portion of the radar signals or of data that is based on the radar signals.

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 circuit includes a signal processing unit to generate a radar map represented by an array with a first index and a second index, and a peak detection unit to identify potential targets in the radar map. Within the peak detection unit, a first peak detection sub-unit scans the radar map along the first index and stores a first detection bitmap that identifies peaks as a function of the first index, and a second peak detection sub-unit scans the radar map along the second index and outputs a second detection bitmap that identifies peaks as a function of the second index. The first detection bitmap and the second detection bitmap identify the peaks using a single bit. A hardware accelerator processes individual bits of the first detection bitmap and of the second detection bitmap.

Abstract: According to an example, an electronic device includes a component, a supply line providing a supply voltage, a transistor with a control input, a linear first control loop, and a non-linear second control loop. The transistor outputs an output voltage to the component depending on a signal applied to the control input. The linear first control loop includes an ADC to convert an analog output voltage level into a digital measurement signal, a controller to generate a digital control signal for the transistor depending on the digital measurement signal, and a DAC to convert the digital control signal into a first analog control signal. The non-linear second control loop is configured to generate a second analog control signal depending on the analog output voltage level. The second analog control signal is superimposed with the first analog control signal and the combined control signals are fed to the control input of the transistor.

Abstract: A method for processing a radar signal includes adjusting a processing clock signal, wherein the processing clock signal determines an operation period of a signal processing circuit, wherein the processing clock signal is determined based on a time window, wherein the size of the time window is determined based on the maximum time available for processing a portion of the radar signal and wherein the end of the time window is determined such that it does not occur during an active transmission portion of the radar system.
