Design and Implementation of 0.28 THz Terahertz Radar System with Ranging Capabilities

This Terahertz radar system has ranging capabilities with high precision. By frequency modulating the K-band supplied by Agilent E8257D PSG analog signal generators, we have achieved a range resolution of approximately 8 cm for targets at a range of several meters. This work demonstrates the feasibility of high-resolution terahertz radar based on an all solid-state approach. This system has great potentiality in bandwidth improving. We could obtain a sub-cm resolution from it by some improvement.
