Abstract: A radar and communication (RadCom) system and a method for vehicles using a fast chirp signal are provided. A radar system includes a phase locked loop (PLL) configured to generate a radar signal, a signal generator configured to generate a communication signal and a mixer configured to mix the radar signal and the communication signal. The system also includes a transmitter configured to transmit an output signal from the mixer, a first switch configured to switch not to transmit the communication signal to the mixer in a radar mode, and a second switch configured to switch to connect a first filter to the PLL when the radar mode ends. Accordingly, RadCom transmission and reception using the fast chirp signal is possible.
