Design and Implementation of FMCW Surveillance Radar Based on Dual Chirps
Elektronika ir Elektrotechnika, 2018 We propose and implement a low-complexity dual-chirp FMCW radar system for surveillance applications. The FMCW radar is suitable for the detection of various positions of multiple targets for the monitoring of concealed humans.

Autonomous FMCW Radar Survey of Antarctic Shear Zone [PDF]
, 2010 Radar survey of the Antarctic shear zone was conducted using an ultra-wideband (2-10 GHz) frequency modulated continuous wave (FMCW) radar. The radar was mounted on a sled and pulled by a robot that was specifically designed to operate in a harsh polar ...

Design of Modular FMCW Radar and Quantization of Its Range Error
Sakarya University Journal of Computer and Information Sciences, 2018 This study presents experimental analysis of range error of modular FMCW (frequency modulated continuous wave) radar operating at C-band. As FMCW utilizes frequency modulation, it can measure both range and speed of targets.

Unsupervised Detection of Multiple Sleep Stages Using a Single FMCW Radar
Applied Sciences, 2023 The paper proposes a unsupervised method for detecting the three stages of sleep—wake, rapid eye movement (REM) sleep, and non-REM sleep—using biosignals obtained from a 61 GHz single frequency modulated continuous wave (FMCW) radar.
