High Resolution FMCW Level Gauge with Narrowband FMCW Radar [PDF]
The Journal of the Korean Institute of Information and Communication Engineering, 2012 Level Gauge using FMCW Radar is widely used and researched in many areas because of contactless, long range and flexibility. However FMCW level gauge requires wideband RF bandwidth for archiving high resolution of cm grade. In this paper we propose a new tx sawtooth waveform and processing algorithm with narrowband RF for wideband performance.

Experimental Comparison of IR-UWB Radar and FMCW Radar for Vital Signs
Sensors, 2020 In this paper, we compare the performances of impulse radio ultra-wideband (IR-UWB) and frequency modulation continuous wave (FMCW) radars in measuring noncontact vital signs such as respiration rate and heart rate. These two type radars have been widely

Metasurface Antennas for FMCW Radar
IEEE Antennas and Wireless Propagation Letters, 2023 Two planar metasurface (MTS) antennas are designed to produce a pattern with optimal illumination in a radar scenario, given the a priori known path of the targets. The antennas are extremely flat, thin, with a monopole feed integrated in the plane of the structure. The monopole serves as a surface-wave (SW) launcher illuminating the slab.

kRadar++: Coarse-to-Fine FMCW Scanning Radar Localisation [PDF]
Sensors, 2020 This paper presents a novel two-stage system which integrates topological localisation candidates from a radar-only place recognition system with precise pose estimation using spectral landmark-based techniques. We prove that the—recently available—seminal radar place recognition (RPR) and scan matching sub-systems are complementary in a style ...

FMCW RADAR SYSTEM FOR TRANSPONDER IDENTIFICATION
Progress In Electromagnetics Research B, 2018 —In this paper, we deal with a frequency modulated continuous wave (FMCW) radar used for localizing and tracking targets by frequency evaluation of the received radar beat signal. The radar system achieved with a primary radar (reader) and a secondary radar (transponder) is addressed as super high frequency (SHF) radio frequency identification (RFID ...
