With the increasing use of radars, inter-radar interference becomes increasingly critical. Severe mutual interference degrades radar signal quality and affects the performance of post-processing, e.g., synthetic aperture radar (SAR) imaging and target tracking. Aiming to deal with mutual interference, we propose an interference mitigation method based on variational mode decomposition (VMD). With the characteristics that the target is a single-frequency sine wave and the interference is a broadband signal, VMD is used for decomposing the radar received signal and separating the target from the interference. Interference mitigation is then implemented in each decomposed mode, and an interference-free signal is obtained through the reconstruction process. Simulation results of multi-target scenarios demonstrate that the proposed method outperforms existing decomposition-based methods. This conclusion is also confirmed by the experimental results on real data.<\/jats:p>","DOI":"10.3390\/rs15030557","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T02:31:11Z","timestamp":1674009071000},"page":"557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Mutual Interference Mitigation of Millimeter-Wave Radar Based on Variational Mode Decomposition and Signal Reconstruction"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3564-6111","authenticated-orcid":false,"given":"Yanbing","family":"Li","sequence":"first","affiliation":[{"name":"School of Electronic and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3233-3526","authenticated-orcid":false,"given":"Bo","family":"Feng","sequence":"additional","affiliation":[{"name":"Beijing Institute of Radio Measurement, Beijing 100854, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4904-1826","authenticated-orcid":false,"given":"Weichuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute for Integrated and Intelligent Systems, Griffith University, Nathan, QLD 4111, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,17]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"MRPT: Millimeter-Wave Radar-based Pedestrian Trajectory-Tracking for Autonomous Urban Driving","volume":"71","author":"Zhang","year":"2021","journal-title":"IEEE Trans.
