    In this paper, optical frequency-chirped signal generation using a high-order optical modulation technique is investigated. An optical frequency comb generator based on optical modulation is utilized as a frequency multiplier. Its multiplication factor of 12 allows designing a 300GHz terahertz-band radar system. An input signal at the central frequency of 25GHz with a chirp bandwidth of 1GHz, 2GHz, and 3GHz provides 6GHz, 12GHz, and 18GHz optical signals at 6th-order harmonics, respectively. A frequency separation of the +6th and -6th-order components is equal to 300 GHz, with a chirp bandwidth of 12GHz and 24GHz. The proposed technique can be used to design high-precision imaging systems.
