Classification: CPC G  H | IPC G  H

Claim 10:
11. A first radar device of a first vehicle comprising:
a Controller Area Network (CAN) interface configured to obtain a first communication message;
a microcontroller unit (MCU) coupled to the CAN interface;
a monolithic microwave integrated circuit (MMIC) coupled to the CAN interface and the MCU and configured to:
modulate the first communication message into a first carrier signal, wherein an operating frequency of the first carrier signal is in an operating band of the first radar device; and
generate a periodic radar signal, wherein the periodic radar signal is a chirp signal;

a transmit antenna coupled to the MMIC and configured to:
send a periodic radar signal;
send a first radar signal at a first time in a current period;
send a second radar signal at a second time in a next period; and
send the first carrier signal to a second vehicle within a time gap between the first time and the second time; and

a receive antenna coupled to the MMIC.
