The Simulation of Terahertz Wave Radar System

From the system simulation perspective, the thesis is about testing the coming multi frequency multiplexing Terahertz radar system and take the 340GHz as the example to design and analyze the system. With the adoption of 21.6 GHz Bandwidth and the foundation of the Matlab/Simulink, the Frequency multiplication module, Mixing module and Quadrature demodulation module, etc., are designed so as to build the Terahertz radar system. Then, the three target points are taken as the example for simulation, and the spectrum charts of radar signal at every phase are obtained. The range image, range image position and resolution of the three target points are consistent with the theoretical value. The detection error and existing problem are analyzed in the end.
