In this paper, a hybrid model is proposed to carry out the interference analysis of UWB EMP coupling responses on the wires to the FMCW radar. First, a field simulation model of the radar is constructed and the wire coupling responses are calculated. Then, the responses are injected into an FMCW circuit model via data format modification. Finally, we use the FFT transform to identify the spectral peak of the intermediate frequency (IF) output signal, which corresponds to the radar\u2019s detection range. The simulation results show that the type of metal wire has the greatest influence on the amplitude of coupling responses. The spectral peak of the IF output changes to the wrong frequency with the increase of injection power. Applying interference at the end of the circuit can more effectively interfere with the detection of the radar. The investigation provides a theoretical basis for the electromagnetic protection design of the radar.<\/jats:p>","DOI":"10.3390\/s22124641","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T04:12:01Z","timestamp":1655871121000},"page":"4641","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Simulation and Analysis of an FMCW Radar against the UWB EMP Coupling Responses on the Wires"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5000-8068","authenticated-orcid":false,"given":"Kaibai","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Missile Engineering, Army Engineering University, Shijiazhuang 050003, China"}]},{"given":"Shaohua","family":"Liu","sequence":"additional","affiliation":[{"name":"Beijing Institute of Systems Engineering and Information Control, Beijing 100020, China"}]},{"given":"Min","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Missile Engineering, Army Engineering University, Shijiazhuang 050003, China"}]},{"given":"Xiaodong","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Ammunition Engineering, Army Engineering University, Shijiazhuang 050003, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1049\/rsn2.12181","article-title":"Vehicle classification applying many-to-one input network architecture in 77-GHz FMCW radar","volume":"16","author":"Jiang","year":"2022","journal-title":"IET Radar Sonar Navig."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Rai, P., Kumar, A., Khan, M., Soumya, J., and Cenkeramaddi, L.R.
