IEEJ Trans. on C, Aug. 2025, [Reviewed] - Wideband Interference Suppression for Automotive mmWave CS Radar: From Algorithm-Based to Learning-Based Approaches
WANG Xiaoyan; KOIZUMI Ryoto; UMEHIRA Masahiro; SUN Ran; TAKEDA Shigeki, In recent times, there has been a significant focus on the development of automotive high-resolution 77GHz CS (Chirp Sequence) radar, a technology essential for autonomous driving. However, with the increasing popularity of vehicle-mounted CS radars, the issue of intensive inter-radar wideband interference has emerged as a significant concern, leading to undesirable missed targe detection. To solve this problem, various algorithm and learning based approaches have been proposed for wideband interference suppression. In this study, we begin by conducting extensive simulations to assess the SINR (Signal to Interference plus Noise Ratio) and execution time of these approaches in highly demanding scenarios involving up to 7 interfering radars. Subsequently, to validate these approaches could generalize to real data, we perform comprehensive experiments on inter-radar interference using multiple 77GHz MIMO (Multiple-Input and Multiple-output) CS radars. The collected real-world interference data is then utilized to validate the generalization capacity of these approaches in terms of SINR, missed detection rate, and false detection rate., The Institute of Electronics, Information and Communication Engineers

NEMOTO Takaya; KOBAYASHI Kaoru; MATSUMOTO Kazunobu; TAKEDA Shigeki; Ran Sun, 線状降水帯に伴う豪雨災害が激甚化・頻発化しており，水災害の増加が懸念されている．破堤の86％は越水が主要因と報告されており，越水しても破堤までの時間を少しでも長くする「粘り強い河川堤防」が求められている．国土交通省は，前記の技術開発目標として，越流水深0.3 m，越流時間3時間を提示している．また，これまでの破堤事例から越流流速3 m/s未満の場合は破堤しないことも報告されている．以上より，本論文では越流水深0.3 m，越流時間3時間に加えて，越流流速3 m/s超の越流水に対し，実規模大の越水実験において，水路内に敷設した2タイプの破砕貝殻層の侵食抑制効果を検証した．その結果，シェルネット型の破砕貝殻層は前記3条件の越流水に対して侵食抑制効果を発揮することを明らかにした．, Japan Society of Civil Engineers

IEEE Access, 2024, [Reviewed] - Experimental Evaluations on Learning-based Inter-radar Wideband Interference Mitigation Method
Koizumi Ryoto; Wang Xiaoyan; Umehira Masahiro; Sun Ran; Takeda Shigeki, In recent years, high-resolution 77GHz band automotive radar, which is indispensable for autonomous driving, has been extensively investigated. In the future, as vehicle-mounted CS (chirp sequence) radars become more and more popular, intensive inter-radar wideband interference will become a serious problem, which results in undesired miss detection of targets. To address this problem, learning-based wideband interference mitigation method has been proposed, and its feasibility has been validated by simulations. In this paper, firstly we evaluated the tradeoff between interference mitigation performance and model training time of the learning-based interference mitigation method in a simulation environment. Secondly, we conducted extensive inter-radar interference experiments by using multiple 77GHz MIMO (Multiple-Input and Multiple-output) CS radars and collected real-world interference data. Finally, we compared the performance of learning-based interference mitigation method with existing algorithm-based methods by real experimental data in terms of SINR (signal to interference plus noise ratio) and MAPE (mean absolute percentage error)., The Institute of Electronics, Information and Communication Engineers

Arai Hoshihiko; Takeda Shigeki; Sun Run, Radio frequency identification (RFID) systems enable us to achieve highly efficient inventory management and inspection work. However, if an RFID reader increases its transmission power to read densely arranged RFID tags in a cardboard box, stray reads of the RFID tags occur. These unwanted reads degrade the overall inventory performance. This letter proposes a reliable reading method for densely arranged RFID tags while suppressing stray reads., The Institute of Electrical Engineers of Japan

Sun Ran; Takeda Shigeki; Kuwahara Yuji; Kobayashi Kaoru, Lead, This paper proposed a process of river-water-level monitoring using a 24 GHz FMCW (Frequency modulated continuous wave) radar. To improve its monitoring accuracy, the use of detected river velocities and the quartile-range limitation method excludes the outliers of calculated distances to water.
