To minimize road accidents, transportation systems need to become more intelligent. Multiple detection of target vehicles under adverse weather conditions is one of the primary challenges of autonomous vehicles. Photonic radar sensors may become the promising technology to detect multiple targets to realize autonomous vehicles. In this work, high-speed photonic radar is designed to detect multiple targets by incorporating a cost-effective wavelength division multiplexing (WDM) scheme. Numerical simulations of the proposed WDM-based photonic radar is demonstrated in terms of received power and signal to noise (SNR) ratio. The performance of the proposed photonic radar is also investigated under diverse weather conditions, particularly low, medium, and thick fog. The proposed photonic radar demonstrated a significant range resolution of 7 cm when the target was placed at 80 m distance from the photonic radar sensor-equipped vehicle. In addition to this, traditional microwave radar is demonstrated to prove the effectiveness of the proposed photonic radar.<\/jats:p>","DOI":"10.3390\/jsan11030049","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T03:34:56Z","timestamp":1661744096000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["High Resolution-Based Coherent Photonic Radar Sensor for Multiple Target Detections"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1715-9689","authenticated-orcid":false,"given":"Sushank","family":"Chaudhary","sequence":"first","affiliation":[{"name":"Wireless Communication Ecosystem Research Unit, Department of Electrical Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4196-6368","authenticated-orcid":false,"given":"Abhishek","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Electronics Technology, Guru Nanak Dev University, Amritsar 143005, India"}]},{"given":"Sunita","family":"Khichar","sequence":"additional","affiliation":[{"name":"Wireless Communication Ecosystem Research Unit, Department of Electrical Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}]},{"given":"Xuan","family":"Tang","sequence":"additional","affiliation":[{"name":"Quanzhou Institute of Equipment and Manufacturing, Chinese Academy of Sciences, Jinjiang 362215, China"}]},{"given":"Xian","family":"Wei","sequence":"additional","affiliation":[{"name":"Software Engineering Institute (SEI), East China Normal University, Shanghai 200050, China"}]},{"given":"Lunchakorn","family":"Wuttisittikulkij","sequence":"additional","affiliation":[{"name":"Wireless Communication Ecosystem Research Unit, Department of Electrical Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,28]]},"reference":[{"key":"ref_1","first-page":"328","article-title":"Pedestrians\u2019 role in road accidents","volume":"7","author":"Baranyai","year":"2017","journal-title":"Int.
