Abstract: A radar device may include a memory to store a program associated with operating the radar device. The radar device may include a decoder to read the program from the memory, and generate a control value and a timestamp based at least in part on the program. The control value may be a value to be provided as an input to a component of the radar device at a time indicated by the timestamp. The radar device may include a first-in first-out (FIFO) buffer to store at least the control value and provide the control value as the input to the component of the radar device at the time indicated by the timestamp.

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: The description below relates to a method for a radar sensor. According to one example implementation, the method comprises receiving configuration data and storing the received configuration data in a first radar chip having multiple transmission channels. The configuration data contain multiple parameter sets for a chirp sequence and association information representing an association of a respective chirp of the chirp sequence with one of the multiple parameter sets. The method further comprises receiving a trigger signal in the first radar chip. The trigger signal indicates the beginning of a respective chirp of the chirp sequence. The transmission channels mentioned are repeatedly configured in sync with the trigger signal, wherein for each chirp of the chirp sequence the transmission channels are configured according to the respective association information. The method further comprises receiving an RF oscillator signal representing the chirp sequence, and supplying the RF oscillator signal to the accordingly configured transmission channels.
