Changzhi Li,Zhengyu Peng,Tien-Yu Huang,Tenglong Fan,Fu-Kang Wang,Tzyy-Sheng Horng,Jose-Maria Munoz-Ferreras,Roberto Gomez-Garcia,Lixin Ran,Jenshan Lin +9 more
TL;DR: This paper reviews recent progress of portable short-range noncontact microwave radar systems for motion detection, positioning, and imaging applications and discusses potential future developments for the next-generation portable smart radar systems.
Journal ArticleDOI
Application of Linear-Frequency-Modulated Continuous-Wave (LFMCW) Radars for Tracking of Vital Signs
TL;DR: This paper focuses on the exploitation of linear-frequency-modulated continuous-wave radars for noncontact range tracking of vital signs, e.g., respiration, and a rigorous mathematical analysis of the operating principle of the LFMCW radar in the context of vital-sign monitoring is detailed.
Journal ArticleDOI
Tunable combline filter with continuous control of center frequency and bandwidth
TL;DR: In this article, a new combline filter structure with a continuous tunability for both the center frequency and bandwidth is presented, which is achieved by placing variable coupling reducers between the filter resonators.
Journal ArticleDOI
Design of sharp-rejection and low-loss wide-band planar filters using signal-interference techniques
TL;DR: In this article, a new class of sharp-rejection, low insertion-loss wide-band planar filters is presented, where the filtering action comes about through the generation of multiple out-of-band power transmission zeros and constructive in-passband signal combinations.
Journal ArticleDOI
A Portable FMCW Interferometry Radar With Programmable Low-IF Architecture for Localization, ISAR Imaging, and Vital Sign Tracking
Zhengyu Peng,Jose-Maria Munoz-Ferreras,Yao Tang,Chenhui Liu,Roberto Gomez-Garcia,Lixin Ran,Changzhi Li +6 more
TL;DR: In this article, a portable radar system for short-range localization, inverse synthetic aperture radar imaging, and vital sign tracking is presented, which incorporates frequency-modulated continuous-wave (FMCW) and interferometry (Doppler) modes.
