This article proposed a two-step accuracy improvement method for multitarget detection in environments with multiple human targets of more than three and strong secondary reflections by the surroundings, especially the walls. Based on the rough detection results acquired by the modified CA-CFAR (MCA-CFAR) processing, the first step achieves the primary false alarm suppression using a short-window accumulation in the time domain. Then, the second step applies the decision confidence on the detection results from the first step to assess the reliability of results for improved accuracy. The two-step accuracy improvement could thus have a higher accuracy through cascading false alarm suppression. The effectiveness and accuracy of the proposed algorithm are verified based on the experimental results.<\/jats:p>","DOI":"10.3390\/rs16050877","type":"journal-article","created":{"date-parts":[[2024,3,1]],"date-time":"2024-03-01T07:36:21Z","timestamp":1709278581000},"page":"877","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Two-Step Accuracy Improvement for Multitarget Detection in Complex Environment Using UWB Radar"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2395-8791","authenticated-orcid":false,"given":"Zhihuan","family":"Liang","sequence":"first","affiliation":[{"name":"School of Information and Communication, Guilin University of Electronic Technology, Guilin 541004, China"},{"name":"Hunan Provincial Key Laboratory of Optic-Electronic Intelligent Measurement and Control, Central South University, Changsha 410083, China"}]},{"given":"Yanghao","family":"Jin","sequence":"additional","affiliation":[{"name":"Academy of Advanced Interdisciplinary Research, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Degui","family":"Yang","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of Optic-Electronic Intelligent Measurement and Control, Central South University, Changsha 410083, China"}]},{"given":"Buge","family":"Liang","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of Optic-Electronic Intelligent Measurement and Control, Central South University, Changsha 410083, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4542-1792","authenticated-orcid":false,"given":"Jinjun","family":"Mo","sequence":"additional","affiliation":[{"name":"School of Information and Communication, Guilin University of Electronic Technology, Guilin 541004, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"14569","DOI":"10.1109\/JSEN.2021.3072607","article-title":"Contact and Remote Breathing Rate Monitoring Techniques: A Review","volume":"21","author":"Ali","year":"2021","journal-title":"IEEE Sens.
