Indoor non-rhythmic human motion classification using a frequency-modulated continuous-wave radar
The Journal of Engineering, 2019 Human motion classification is widely used in intelligent house, surveillance, search and rescue operation, intelligent house, and elder monitoring. In this study, a frequency-modulated continuous-wave radar is utilised to classify non-rhythmic human ...

Proposal of multiple access FMCW radar for inter-radar interference avoidance
The Journal of Engineering, 2019 Inter-radar interference will be a crucial problem when a number of frequency modulated continuous wave (FMCW) radars are densely deployed in future, since it can cause miss detection and false detection of the target due to wideband interference and ...

American Journal of Hematology, EarlyView.ABSTRACT Plasmodium vivax‐associated anemia is a multifactorial clinical outcome, in which the destruction of uninfected red blood cells (uRBCs) plays a major role in disease development and severity. Here, we identified autoantibody targets within the extracellular loops of Band 3 (B3), a major erythrocyte transmembrane protein.

Space scanning FMCW-based two-dimensional frequency diverse array radar
The Journal of Engineering, 2019 The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...

A Flexible K‐Band FMCW Radar Prototype for Low‐RCS Nano‐Drone Detection
IET Radar, Sonar & NavigationNano‐drones are insect‐like drones used to provide intelligence through their capability of intrusion and ability to carry small sensors. They pose a defence and security threat and can potentially violate secure establishments and privacy rights.

Forensic Application of FM-CW and Pulse Radar [PDF]
Journal of Environmental & Engineering Geophysics, 2003 Ground-penetrating radar (GPR) technology has supplied vital assistance in criminal investigations. However, law enforcement personnel desire further developments such that the technology is rapidly deployable, and that it provides both a simple user interface and sophisticated target identification.

Investigation on reason of range profile distortion of plasma sheath target
The Journal of Engineering, 2019 The range profile of the plasma sheath target is always found to be distorted when using the linear frequency modulation signal as the radar detection signal. As a result, the detection and tracking of the target became hard, or even failure. Here, three

Business Strategy and the Environment, EarlyView.ABSTRACT Eco‐labels and sustainability rating scales are widely used to communicate product sustainability, yet it remains unclear whether combining these signals enhances or undermines consumer responses. Drawing on signaling theory, this study examines how eco‐label familiarity and the presence of a sustainability rating scale jointly shape consumer ...
