However, it requires the detecting platform or target to move uniformly along a straight path. To circumvent the restrictions, a new adaptive basis functions (ABFs) approach is proposed in this article. It permits the detection platform to search for a possible target at different speeds along any course. The ABFs are constructed using the real-time data of the onboard triaxial fluxgate, GPS module, and attitude gyro. Based on the pseudo-energy of an apparent target signal, the constant false alarm rate (CFAR) method is employed to judge whether a target is present. Moreover, by defining the pixel as a relative possibility for a target at a geographic location, a magnetic anomaly target imaging scheme is introduced by displaying the pixels onto the searching area. On-site experimental data are utilized to demonstrate the proposed approach. Compared with the traditional OBFs method, the present ABFs approach can substantially improve the detection possibility and reduce false alarms.<\/jats:p>","DOI":"10.3390\/rs16020363","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T11:37:18Z","timestamp":1705405038000},"page":"363","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Adaptive Basis Function Method for the Detection of an Undersurface Magnetic Anomaly Target"],"prefix":"10.3390","volume":"16","author":[{"given":"Xingen","family":"Liu","sequence":"first","affiliation":[{"name":"School of Electronics, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zifan","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Electronics, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8380-9926","authenticated-orcid":false,"given":"Changping","family":"Du","sequence":"additional","affiliation":[{"name":"School of Electronics, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0815-5122","authenticated-orcid":false,"given":"Xiang","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Electronics, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0644-6698","authenticated-orcid":false,"given":"Hong","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Electronics, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyao","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Electronics, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"17868","DOI":"10.1109\/JSEN.2023.3294498","article-title":"Theories, Applications, and Expectations for Magnetic Anomaly Detection Technology: A Review","volume":"23","author":"Liu","year":"2023","journal-title":"IEEE Sens.
