Photonic-based FMCW Radar System Using Optical Signal Delay Module

摘要

A photonic based FMCW radar system using an optical signal delay module according to the present invention is provided. The photonic-based FMCW radar system includes an optical coupler for performing frequency multiplication; an optical signal delay module operatively coupled to the optical coupler and configured to selectively delay an optical signal; and a signal processing unit configured to obtain a target range (Rt) associated with the position of the target when the delay value selected by the optical signal delay module is applied to the receiving unit, wherein the distance and bandwidth of the radar system and the target are Even if it increases, real-time data processing is possible with minimal memory and short required time.
