Given its capacity to generate 2-D fine images of observation areas, very high resolution
(VHR) synthetic aperture radar (SAR) has become increasingly popular in myriad fields …

The electromagnetic spectrum plays a fundamental role in the development of the digital
society. It enables wireless communications (either between humans or machines) and …

In recent years, our research group has been devoting substantial efforts to the research and
development of active all-solid-state electronic terahertz (THz) continuous wave imaging …

Terahertz (THz) radar has been considered as a new solution to the dilemmas in performing
ultra-high-resolution imaging and obtaining highly precise target information. In this work, a …

In this paper we present the first high resolution SAR measurements performed in the lower
terahertz region with the MIRANDA-300 system. The millimeter wave FMCW radar is …

Radar sensors have been widely used to estimate speed and displacement of remote
targets. A novel market for contactless radar sensing is emerging in the field of …

This paper presents a novel transmitter system for applications operating in the frequency
region around 300 GHz. A relatively simple packaging approach is taken, allowing for a …

A self-designed all-solid-state electronic 3-D millimeter-wave imaging radar is demonstrated
and applied in holographic imaging for nondestructive testing of polymer materials. Full …

We present the principle of a terahertz-wave radar and its proof-of-concept experimental
verification. The radar is based on a 522 GHz resonant-tunneling-diode oscillator, whose …

Thin structured surfaces allow flexible control over the propagation of electromagnetic
waves. Focusing and polarization state analysis are among functions, required for effective …
