Abstract: A device may include a test signal generator and a receive antenna input. The device may include a switchable impedance matching circuit, coupled to the test signal generator and to a receive chain, to cause an impedance matching between the test signal generator and a component of the receive chain to be increased during a monitoring phase. The impedance matching during the monitoring phase enables one or more measurements based on a test signal generated by the test signal generator. The switchable impedance matching circuit may cause a partial impedance mismatching between the test signal generator and the component of the receive chain during a verification phase associated with verifying a return of the switchable impedance matching circuit to an impedance matching caused during the operational phase. The device may include a control circuit to verify operation of the returning of the switchable impedance matching circuit in the verification phase.

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 method for calibrating a radar system includes generating an RF oscillator signal and distributing the RF oscillator signal to a plurality of phase shifters each providing a respective phase-shifted RF oscillator signal; receiving the phase-shifted RF oscillator signals by corresponding radar chips and radiating the phase-shifted RF oscillator signal via a first RF output channel of a first one of the radar chips; receiving a back-scattered signal by at least one RF input channel of each radar chip and generating a plurality of base-band signals by down-converting the received signals into a base band using the phase-shifted RF oscillator signals received by the corresponding radar chips; determining a phase for each base-band signal; and adjusting the phase shifts caused by the phase shifters such that the phases of the base-band signals match a predefined phase-over-antenna-position characteristic.

Abstract: A radar system includes a signal generator configured to generate an RF signal; a modulator configured to generate an RF test signal by modulating the RF signal with a test signal; a transmitting channel configured to generate an RF output signal based on the RF signal; and a receiving channel configured to receive an antenna signal and the RF test signal and down-convert a superposition of the two signals to baseband by means of a mixer in order to obtain a baseband signal. The radar system further includes an analog-to-digital converter configured to generate a digital radar signal based on the baseband signal, and a computing unit configured to filter the digital radar signal by means of a digital filter, wherein the filter characteristic of the digital filter has a pass band, a transition band, and a stop band. The test signal has a frequency in the transition band.
