In our proposed sensor system, a wideband Boolean-chaos signal is used as the probe signal, and a pair of leaky coaxial cables (LCXs) is applied for transmitting the probe signal and receiving the echo signal, respectively. By correlating the chaotic echo signal with its delayed duplicate and comparing the correlation traces before and after intrusion, the intruder can be accurately located. Experimental results demonstrate the proposed sensor can simultaneously detect multiple intruders. The range resolution reaches 30 cm, whilst the dynamic range can achieve 50 dB. In addition, this sensor possesses the excellent anti-interference performance to the noise and uncorrelated chaotic signal, which makes it show robust performance in the detection environment with noise or multiple chaotic LCX sensors cooperation.<\/jats:p>","DOI":"10.3390\/s18124154","type":"journal-article","created":{"date-parts":[[2018,11,27]],"date-time":"2018-11-27T03:31:33Z","timestamp":1543289493000},"page":"4154","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A High-Resolution Leaky Coaxial Cable Sensor Using a Wideband Chaotic Signal"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6751-5928","authenticated-orcid":false,"given":"Hang","family":"Xu","sequence":"first","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Jun","family":"Qiao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Jianguo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Hong","family":"Han","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Jingxia","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Li","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Bingjie","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Transducers &amp; Intelligent Control System, Ministry of Education and Shanxi Province, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"College of Physics &amp; Optoelectronics, Taiyuan University of Technology, Taiyuan 030024, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1109\/62.756080","article-title":"Security Applications of Computer Vision","volume":"14","author":"Sage","year":"1999","journal-title":"IEEE Aerosp.
