Abstract: A radar semiconductor chip includes a radar circuit component configured to generate at least part of a frequency-modulated ramp signal or process at least part of a reflected frequency-modulated ramp signal according to a control parameter; a memory configured to store a sequencing program associated with regulating the control parameter, wherein the sequencing program specifies a first data source, external to the sequencing program, that is configured to provide a first data value corresponding to the control parameter; and a decoder configured to read the sequencing program, access the first data value from the first data source specified by the sequencing program, derive a first control value for the control parameter from the first data value, and provide the first control value to the radar circuit component. The radar circuit component regulates a controlled circuit function in accordance with the control parameter based on the first control value.

Abstract: A radar system includes a local oscillator for generating a local oscillator signal, transmission channels, and a reception channel. The transmission channels are designed to generate and output RF radar signals based on the local oscillator signal The transmission channels have phase shifters for setting the phase of the RF radar signals. The reception channel is designed to receive an RF signal and to convert it into a baseband signal by using the local oscillator signal supplied thereto. A method includes operating the local oscillator in a CW mode, setting a specific combination of phase shifts for the phase shifters of the transmission channels, altering the phase of the local oscillator signal supplied to the reception channel or of the phase shifts of the phase shifters by a phase offset, and ascertaining that phase offset for which the baseband signal at least approximately assumes a maximum.

Abstract: A method includes: receiving a reflected radar signal including a first radar chirp signal during a first chirp time period and a second radar chirp signal during a second chirp time period; downconverting the reflected radar signal to form a baseband signal; adding a DC offset to the baseband signal to form a DC offset baseband signal, adding the DC offset including adding a first DC offset to the baseband signal during the first chirp time period, and adding a second DC offset to the baseband signal during the second chirp time period, where the first DC offset is different from the second DC offset; and digitizing the DC offset baseband signal using an analog-to-digital converter to form a digitized baseband signal.
