Dynamic Gesture Recognition with a Terahertz Radar Based on Range Profile Sequences and Doppler Signatures [PDF]

open access: yesSensors, 2017
The frequency of terahertz radar ranges from 0.1 THz to 10 THz, which is higher than that of microwaves. Multi-modal signals, including high-resolution range profile (HRRP) and Doppler signatures, can be acquired by the terahertz radar system.

Absolute and Precise Terahertz-Wave Radar Based on an Amplitude-Modulated Resonant-Tunneling-Diode Oscillator

open access: yesPhotonics, 2018
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 terahertz output power can be easily modulated by superimposing the ...

Analysis of terahertz wave penetration capacity to 2D conductive cylinder coated with steady-state parabolic distribution plasma media

open access: yesResults in Physics, 2021
Terahertz waves have long been considered as the most efficient of many solutions to solve the blackout problem for the reason that terahertz waves have much stronger penetration than microwaves.
