Abstract :
A terahertz (THz) radar system with the highest frequency up to 0.22THz is described in this paper. The system is built based on the microwave up-conversion technology and with a good performance in operating range. The radar cross section (RCS) measurement of different objects, namely, corner reflector, cylinder, rectangular plate and a scale car model, is performed based on the THz system. By the comparison of the measurement results of the rectangular plates with different surface characterization, a conclusion is reached that the detailed surface has a considerable influence on RCS values. Moreover, the RCS values of the car model with different incident angles are obtained based on the measurement experiments.
