Communication system for a tooth-mounted RF sensor used for continuous monitoring of nutrient intake [PDF]

open access: yes, 2019
In this Thesis, the communication system of a wearable device that monitors the user’s diet is studied. Based in a novel RF metamaterial-based mouth sensor, different decisions have to be made concerning the system’s technologies, such as the power ...

FMCW Interference Waveform Estimation Based on Intentional Local Interference for Automotive Radars [PDF]

open access: yesJournal of Electromagnetic Engineering and Science
We propose a new method to estimate the waveforms of frequency-modulated continuous-wave (FMCW) interferers by intentional interference. The proposed method utilizes the crossing interference of FMCW radar by adaptive waveform configuration.

leave a trace - A People Tracking System Meets Anomaly Detection

open access: yes, 2017
Video surveillance always had a negative connotation, among others because of the loss of privacy and because it may not automatically increase public safety. If it was able to detect atypical (i.e.

Analiza kontinualnih frekvencijski modulisanih radarskih signala primenom vremensko-frekvencijskih transformacija i korelacionih tehnika / FMCW radar signal analysis by time-frequency representations and correlation techniques

open access: yesVojnotehnički Glasnik, 2007
U radu su analizirana dva metoda za detekciju i procenu parametara radarskih signala s malom verovatnoćom presretanja, pri čemu ne postoji saradnja između prijemnika i predajnika.

An Adversarial Super-Resolution Remedy for Radar Design Trade-offs

open access: yes, 2019
Radar is of vital importance in many fields, such as autonomous driving, safety and surveillance applications. However, it suffers from stringent constraints on its design parametrization leading to multiple trade-offs. For example, the bandwidth in FMCW

FMCW-based contactless heart rate monitoring

open access: yesScientific Reports
Heart disease is a significant global health issue. Traditional methods for heart rate monitoring typically require close physical contact, which limits the continuity and convenience of monitoring. To achieve real-time, non-contact heartbeat monitoring, researchers have introduced millimeter-wave radar technology.
