1. A device for a first radar sensor comprising:
generate a first beacon signal and a first transmission signal with a linear frequency chirp modulation, wherein the first beacon signal includes information indicating at least one of a first timing pattern for the first transmission signal and a first frequency range in a predetermined frequency band,
output, to a radar antenna, the first beacon signal during a first part of a scan period, and
output, to the radar antenna, the first transmission signal during a second part of the scan period;
reception circuitry configured to receive reflection signals corresponding to reflection of the first transmission signal from one or more physical objects; and
control circuitry configured to select at least one of the first frequency range within the predetermined frequency band and the first timing pattern for the first transmission signal;
wherein the device is configured to:
receive an indicator signal from a second radar sensor, wherein the indicator signal comprises information indicative of at least one of a second frequency range and a second timing pattern in use by the second radar sensor for transmission of second transmission signals;
determine, based on the indicator signal, the at least one of the second frequency range and the second timing pattern in use by the second radar sensor for transmission of the second transmission signals; and
select the at least one of the first frequency range within the predetermined frequency band and the first timing pattern for the first transmission signals such that the selected at least one of the first frequency range and the first timing pattern are different from a corresponding at least one of the second frequency range and the second timing pattern of the second transmission signals, respectively.
