Abstract: A radar system includes a radio frequency (RF) receiver configured to receive radar data at a plurality of receive antennae. A fast Fourier transform (FFT) circuit is coupled to the RF receiver. The FFT circuit is configured to perform a FFT on the radar data to provide a stream of complex values. The stream of complex values includes a plurality of Range-Doppler coordinate pairs that pertain to the plurality of receive antennae. A memory is coupled to the FFT circuit. The memory is configured to store three-dimensional (3D) radar data. A Direct Memory Access circuit (DMA) is coupled to the memory.

Abstract: A radar system including a direct memory access (DMA). The DMA includes a bus interface including control/status registers and data-in/data-out registers. The DMA also includes potential object queue memory coupled to the bus interface, and a potential object queue logic coupled to the potential object queue memory. The DMA also includes boundary checking circuitry configured to detect whether any portion of a DMA read configuration is greater than a maximum range bin or less than a minimum range bin. The boundary checking circuitry detects whether any portion of the DMA read configuration is greater than a maximum Doppler bin or less than a minimum Doppler bin.

Abstract: A method of handling radar signals of a radar system having a plurality of antennas is provided. The method may include generating a plurality of time-based radar signals based on a radar signal received by an associated antenna of the plurality of antennas, and transforming each time-based radar signal of the time-based radar signals into radar signals that each comprise a plurality of pairs of a frequency-based-value and an associated intensity value. The method includes storing the frequency-based-values and the intensity values of one frequency-based radar signal corresponding to one time-based radar signal of one antenna of the plurality of antennas; and storing each intensity value of the plurality of intensity values of another of the plurality of frequency-based radar signals based on a corresponding intensity value of the one frequency-based radar signal, wherein a stored representation of the intensity value of the other of the plurality of frequency-based radar signals has fewer bits than the corresponding stored intensity value.

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 of handling radar signals of a radar system having a plurality of antennas is provided. The method includes processing a plurality of radar signals for determining a distance between the radar system and at least one target and a velocity of the at least one target, thereby forming a plurality of processed radar signals. Each radar signal of the plurality of radar signals is received by an associated antenna of the plurality of antennas. The plurality of processed radar signals are digitally beamformed for at least one beam direction, thereby forming a plurality of beamformed radar signals. The plurality of beamformed radar signals are summed from the plurality of antennas per beam direction.

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.
