Unified Model and Survey on Modulation Schemes for Next-Generation Automotive Radar Systems

Remote Sensing
Commercial automotive radar systems for advanced driver assistance systems (ADASs) have relied on frequency-modulated continuous wave (FMCW) waveforms for years due to their low-cost hardware, simple signal processing, and established academic and ...

FMCW-autotutkan kulmaresoluution mittaaminen

, 2022
Tiivistelmä. Tämän kandidaatintyön aiheena on FMCW-autotutkan toimintaan perehtyminen. Työssä käydään läpi autotutkien historiaa ja nykytilannetta, selitetään FMCW-tutkan toimintaperiaate ja edut muihin tutkatyyppeihin verrattuna, ja suoritetaan kokeellinen mittaus tutkan kulmaresoluution arvioimiseksi.

Multi-Person Motion Tracking via RF Body Reflections [PDF]

, 2014
Recently, we have witnessed the emergence of technologies that can localize a user and track her gestures based purely on radio reflections off the person's body. These technologies work even if the user is behind a wall or obstruction.

Milimeterwave FMCW radar design

, 2020
In traffic radar system, Frequency Modulated Continuous Wave (FMCW) will be used since these radars are preferred in short distance and high range resolution systems.The system to be constructed is not only a system operating with Doppler principle and detection of speed; on the contrary a functional radar is planned to be produced.

Millimeter-Wave OFDM-FMCW Radar-Communication Integration System Design

Remote Sensing
Frequency-modulated continuous wave (FMCW) and orthogonal frequency-division multiplexing (OFDM) technologies play significant roles in millimeter-wave radar and communication. Their combinations, however, are understudied in the literature.

Broadband High-Linear FMCW Light Source Based on Spectral Stitching

Photonics
The key to realizing a high-performance frequency-modulated continuous wave (FMCW) laser frequency-sweeping light source is how to extend the frequency-swept bandwidth and eliminate the effect of nonlinearity.
