The proposed radar system relies heavily on a field\u2010programmable gate array (FPGA) platform. The Xilinx FPGA Kintex\u20107 (KC705) board is employed to integrate the main functionalities of the radar system, such as the generation and acquisition of a UWB signal. The generated signal is a monocycle signal, which has an ultra\u2010wide bandwidth. Due to the UWB nature of this signal, the radar system achieves better penetration ability, as well as high imaging resolution. However, the major challenge of a UWB radar system lies in the stage of digitization, as it requires a high sampling rate analog\u2010to\u2010digital converter (ADC). In fact, such a chip is very expensive. Hence, to reach a high sampling resolution using a low\u2010cost and low\u2010speed ADC, an efficient sampling strategy is implemented. In contrast to other UWB sampling methods, which require a hardware delay line chip, the new sampling scheme depends only on the FPGA firmware to realize a combination of real\u2010time and equivalent\u2010time sampling, which provides better jitter performance. Finally, to demonstrate the imaging capability, experimental tests are conducted in an indoor environment while human targets are located in different places. The measurement results revealed that the proposed radar system has the ability to provide 2D images that accurately determine the location of the target.<\/jats:p>","DOI":"10.1002\/dac.5510","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T00:04:27Z","timestamp":1683245067000},"update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["An efficient FPGA\u2010based implementation of UWB radar system for through\u2010wall imaging"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0002-3111-2713","authenticated-orcid":false,"given":"Mohamed","family":"Saad","sequence":"first","affiliation":[{"name":"Laboratoire Syst\u00e8mes \u00c9lectroniques et Num\u00e9riques \u00c9cole Militaire Polytechnique Algiers Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdelmadjid","family":"Maali","sequence":"additional","affiliation":[{"name":"Laboratoire Syst\u00e8mes \u00c9lectroniques et Num\u00e9riques \u00c9cole Militaire Polytechnique Algiers Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0001-6207-7626","authenticated-orcid":false,"given":"Mohamed","family":"Salah Azzaz","sequence":"additional","affiliation":[{"name":"Laboratoire Syst\u00e8mes \u00c9lectroniques et Num\u00e9riques \u00c9cole Militaire Polytechnique Algiers Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustapha","family":"Benssalah","sequence":"additional","affiliation":[{"name":"Laboratoire Traitement du Signal \u00c9cole Militaire Polytechnique Algiers Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,5,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfranklin.2008.01.005"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2013.10.016"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2019.05.109"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2021.153807"},{"key":"e_1_2_8_6_1","unstructured":"MahfouzM FathyA YangY AliEE BadawiA.See\u2010through\u2010wall imaging using ultra wideband pulse systems.
