High-resolution three-dimensional imaging radar [PDF]

open access: yes, 2010
A three-dimensional imaging radar operating at high frequency e.g., 670 GHz, is disclosed. The active target illumination inherent in radar solves the problem of low signal power and narrow-band detection by using submillimeter heterodyne mixer receivers.

Single Antenna Radar Sensor with FMCW Radar Transceiver IC

open access: yesThe Journal of Korean Institute of Electromagnetic Engineering and Science, 2018
This paper presents a single antenna radar sensor with Ku-band radar transceiver IC realized in 0.13 μm CMOS processes. In the radar receiver, a sensitivity time control using a DC offset cancellation feedback loop is employed for constant SNR irrelevant on the distance.
