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.
