Method for radar interference mitigation

An apparatus comprising:

• a first radar sensor device including:
• a transmitter part to transmit radar wave signals;
• and
• a receiver part to receive radar wave signals;
• at least one processor;
• and
• a computer-readable storage medium storing instructions that, when executed by the at least one processor, cause the at least one processor to:
• determine, by the first radar sensor device on a vehicle and based on information received from multiple sources, information about a driving scenario in a surrounding environment of the vehicle, wherein the information received from multiple sources includes:
• information received from at least one component of a road infrastructure through a vehicle-to-infrastructure communication, wherein the at least one component of the road infrastructure includes one of a lane marking, a road sign, and a traffic light;
• information received from a first radar signal from a second radar sensor device on at least one second vehicle through a vehicle-to-vehicle communication;
• information received from a second radar signal from a third radar sensor device on at least one third vehicle without communication capability;
• determining radar parameter information of the second radar sensor device determined by analyzing the first radar signal received from the second sensor radar device;
• and
• determining radar parameter information of the third radar sensor device by analyzing the second radar signal received from the third radar sensor device, wherein
• based on the determined radar parameter information about the driving scenario, determine how to change at least one radar parameter of the first radar sensor device to avoid a possible radar interference;
• and
• change the at least one radar parameter according to the determination.
