Terahertz Radar with High Resolution Range Profile
2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz), 2021In this paper, the performance of terahertz (THz) radar based on high resolution range profile (HRRP) is described. This terahertz radar, developed for the high resolution imaging under the complex environment such as sand-dust weather and so on, operates at 230GHz over multiple GHz of bandwidth.

Imaging terahertz radar for security applications
SPIE Proceedings, 2008Detection of concealed threats is a key issue in public security. In short range applications, passive imagers operating at millimeter wavelengths fulfill this task. However, for larger distances, they will suffer from limited spatial resolution. We will describe the design and performance of 0.8-THz imaging radar that is capable to detect concealed ...

Design and implementation of spaceborne Terahertz cloud radar
2016 46th European Microwave Conference (EuMC), 2016Spaceborne cloud radar is a kind of active remote sensing instrument. It can achieve all-day, all-weather continuous observations of global cloud vertical structure and cloud liquid water, ice water content. Compared to the current millimeter-wave cloud radar, terahertz cloud radar has a higher sensitivity and a shorter wavelength which is closer to ...

A sub-terahertz real aperture imaging radar
2014 IEEE Radar Conference, 2014Due to the lack of high-power sources along with strong electromagnetic absorption by water vapor at frequencies between ~100 GHz and ~10 THz, there are very few radar systems, or any other systems for that matter, operating in this region of the spectrum. For this reason, it is sometimes referred to as the terahertz gap. Source technology, however, is

A terahertz synthetic aperture radar with centimeter-level resolution
2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz), 2021Compared with microwave synthetic aperture radar (SAR), terahertz (THz) SAR has advantages of higher frequency, higher resolution, higher frame rate and so on. Meanwhile, THz SAR is able to penetrate through cloud, smoke and dust with low attenuation, which leads to the applications of high-resolution imaging and target recognition in complex ...

A random phase compensation method for terahertz radar
2016 CIE International Conference on Radar (RADAR), 2016The random phase errors existing in the terahertz (THz) radar system, usually lead to the range profile broadened and defocused, which should be compensated. In this paper, a compensation method based on Bayesian compressive sensing (BCS) is proposed. Firstly, the reconstruction model containing the random phase errors is established. Subsequently, the
