    In this paper, we demonstrate a 300-GHz FM-CW radar using optical modulation technology. An optical frequency comb based on the optical modulation is utilized as a broadband frequency multiplier with a factor of 12. At a central frequency of 300 GHz, we generate a 12-GHz-bandwidth FM-CW signal with a pulse duration of 10 μs, realizing a precise ranging with a resolution of several centimeters. We show that the optical frequency comb generator is capable of generating larger bandwidth FM-CW signals.
