FMCW Radar-based Vital Signal Monitoring Technique Using Adaptive Range-bin Selection
International Radar Conference, 2023This paper aims to propose a signal processing technique for non-contact sensing of vital signs such as respiration and heart-rate using FMCW radar. Existing studies have limitation of only detecting vital signs for a fixed target, but in this study, we ...

FMCW-LIO: A Doppler LiDAR-Inertial Odometry
IEEE Robotics and Automation LettersConventional LiDAR-inertial odometry (LIO) or SLAM methods heavily rely on geometric features of environments, as LiDARs primarily provide range measurements instead of motion measurements.

A Dual-Frequency Phase Ambiguity Resolution Method for FMCW Radar High-Accuracy Ranging
IEEE Transactions on Instrumentation and MeasurementHaving the correct resolution of phase ambiguity is critical in achieving high-accuracy ranging for frequency-modulated continuous-wave (FMCW) radar. An incorrect resolution may result in cycle slips in ranging results.

Hypothesis Testing on FMCW and OFDM for Joint Communication and Radar in IEEE 802.11bd
2023 IEEE International Conference on Communications Workshops (ICC Workshops), 2023In this paper, we provide a theoretical study on the receiver operating characteristic (ROC) of frequency-modulated continuous-wave (FMCW)-based radars, orthogonal frequency division multiplexing (OFDM)-based radars and the superposition of FMCW waveform

Frequency modulated continuous wave (FMCW) radar uses a very low probability of intercept waveform, which is also well suited to make good use of simple solid-state transmitters. FMCW is finding applications in such diverse fields as naval tactical navigation radars, smart ammunition sensors and automotive radars.

Frequency Modulated Continuous Wave (FMCW) radars have been used by snow scientists for the past 30 years. This radar technology provides a promising alternative to point measurements, as properties such as snow depth can be measured quickly and non-destructively. Recent advances in microwave FMCW radar technology have resulted in lightweight, portable

Pandora multifrequency FMCW/SFCW radar
Record of the IEEE 2000 International Radar Conference [Cat. No. 00CH37037], 2002This paper pertains to the design aspects of a multifrequency FMCW/SFCW radar with emphasis on the engineering problems involved in its implementation. The paper mostly discusses the FMCW mode of operation. This system can also be used for generating SFCW signals. The implications in this mode are also examined. In the FMCW mode, this radar generates 8

Interference Characterization in FMCW radars
2020 IEEE Radar Conference (RadarConf20), 2020As the penetration levels of Automotive radars increase so will the problem of mutual interference. It is important to understand how this will affect the performance of current radar technology. The aim of this paper is the statistical characterization of interference in the context of fast chirp FMCW radar. We focus on two categories of interference:

FMCW linearizer bandwidth requirements
Proceedings of the 1991 IEEE National Radar Conference, 2002The frequency-modulated continuous-wave (FMCW) linearity achievable as a function of the bandwidth of the linearizing frequency sweep modulator or linearizer is analyzed. This analysis pertains to millimeter-wave (MMW) radar seekers for short range air-to-ground missiles that employ the FMCW waveform because of weight, volume, and prime power ...
