Dong, Xichao (author), Zhao, Zewei (author), Wang, Yupei (author), Zeng, Tao (author), Wang, J. (author), Sui, Yi (author)Recently, frequency-modulated continuous-wave (FMCW) radar-based hand gesture recognition (HGR) using deep learning has achieved favorable performance. However, many existing methods use extracted features separately, i.e., using one of the range, Doppler, azimuth, or elevation angle information, or a combination of any two, to train...journal article 2022

Wang, J. (author), Ding, Ming (author), Yarovoy, Alexander (author)In this paper, the interference mitigation for Frequency Modulated Continuous Wave (FMCW) radar system with a dechirping receiver is investigated. After dechirping operation, the scattered signals from targets result in beat signals, i.e., the sum of complex exponentials while the interferences lead to chirp-like short pulses. Taking...journal article 2022

(author), Zhang, Kouchi (author), Poelma, René H. (author)High-performance IC-to-antenna interconnection is one of the key enablers for the mass production of high-end millimeter wave (mmW) radar systems above 100 GHz. In this work, a radar system with an on-package antenna array working at 122 GHz is presented. The antenna is placed on top of the molded package and the antenna-to-chip interconnection...journal article 2022

Wang, J. (author)In this paper, constant false alarm rate (CFAR) detector-based approaches are proposed for interference mitigation of Frequency modulated continuous wave (FMCW) radars. The proposed methods exploit the fact that after dechirping and low-pass filtering operations the targets' beat signals of FMCW radars are composed of exponential sinusoidal...journal article 2022

Wang, J. (author), Ding, M. (author), Yarovoy, Alexander (author)A novel matrix-pencil (MP)-based interference mitigation approach for frequency-modulated continuous-wave (FMCW) radars is proposed in this article. The interference-contaminated segment of the beat signal is first cut out, and then, the signal samples in the cutout region are reconstructed by modeling the beat signal as a sum of complex...journal article 2021

Wan, Lin (author)In the last two decades, radar-based contactless vital signs monitoring (heartbeat and respiration rate) has raised increasing interest as an emerging approach for healthcare and complementary for other more established technologies. Heartbeat and respiration induce only very subtle rhythmic changes in the reflected radar signature, whereas the...master thesis 2020

Wan, Siyan (author)Currently, most of FMCW radar systems for target detection and localization are based on the radar system with multiple receiving antennas, but little based on the SISO system. In this project, we will show a unique signal processing pipeline based on the 8 GHz SISO FMCW radar system. An advanced algorithm of multi-target detection and tracking...master thesis 2020

van der Geugten, Gerald (author)In this thesis a deterministic wave model is used to reconstruct and predict the sea surface motion from FMCW (Frequency Modulated Continuous Wave) radar data, produced by Radac. The deterministic model that is used to do this is based on the linear wave theory. The radar is looking horizontally straight towards the waves in 5 separate beam...master thesis 2020

Yun, Joongsup (author), Anderson, David (author), Fioranelli, F. (author)This paper presents parametric investigation results on a staring FMCW radar system which targets drone swarms. The parametric investigation has been carried out by using the RAPID-SIM which facilitates system-level analysis of drone swarms' radar signatures. This paper explains concepts of the simulator's each module and also covers two...conference paper 2020

Shrestha, Aman (author), Li, Haobo (author), Kernec, Julien le (author), Fioranelli, F. (author)Recognition of human movements with radar for ambient activity monitoring is a developed area of research that yet presents outstanding challenges to address. In real environments, activities and movements are performed with seamless motion, with continuous transitions between activities of different duration and a large range of dynamic...journal article 2020

Hehenberger, Simon P. (author), Yarovoy, Alexander (author), Stelzer, Andreas (author)In state-of-the-art frequency-modulated continuous-wave (FMCW) multiple-input multiple-output (MIMO) radar systems, antennas are usually designed based on microstrip technology. They are arranged in uniform arrays such that the synthesized virtual array maximizes the angular resolution. This paper presents the design of a 77-GHz FMCW MIMO...conference paper 2020

Nowak, Aleksander (author), Naus, Krzysztof (author), Maksimiuk, D. (author)A market for small drones is developing very fast. They are used for leisure activities and exploited in commercial applications. However, there is a growing concern for accidental or even criminal misuses of these platforms. Dangerous incidents with drones are appearing more often, and have caused many institutions to start thinking about...journal article 2019

Truong, Han (author)This thesis will focus on an 24 GHz indoor human presence detection radar with an optically transparent dielectric resonator antenna (DRA) applied in an enclosed light source. The DRA was studied extensively by simulations and measurements and demonstrated to suffer from blind spots for radar implementation because of the light bulb housing. To...master thesis 2018

Maas, J.B. (author), van Gent, R.N.H.W. (author), Hoekstra, J.M. (author)Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...conference paper 2018

Sanka, Sasanka (author)Automotive radar is a key element in Advanced Driver Assistance Systems (ADAS). With the growth of Automotive industry, there is a high demand for the sensors used in assisting systems. As the number of sensors increases, probability that these systems being in close proximity will also increase. This will lead to situations where in multiple...master thesis 2017

Naulais, C. (author)General Aviation aircraft mostly fly with Visual Flight Rules (VFR). These are rules in aviation that permit the pilot to fly on sight if the weather conditions offer enough visibility for the pilot to perform the following tasks visually: collision avoidance with terrain or other airborne object, navigation and attitude determination. VFR...master thesis 2015
