摘要
Abstract
The design and realization of a terahertz(THz) radar system with 0. 14 THz carrier frequency and 5 GHz bandwidth have been presented. The Ka band signal was frequency-doubled to be used as the local oscillator signal for sub-harmonic mixer in the system's transceiver chain. For the transmitted signal was a linearly frequency-modulated continuous-wave (LFM-CW), the dechirp technique was used in the THz radar receiver front end. By using this THz radar system, 3 cm high resolution range profiles were obtained as well as inverse synthetic aperture radar(ISAR) images, which exactly represent the subtle features of targets.关键词
