According to the distribution of a rotating magnetic field and the phase angle measuring principle, we put forward a new magnetic source structure design of a multiple rotating permanent magnet array by adjusting the spacing d, the rotating speed \u03c9 and the initial rotation angle \u03c6, and then verified the mathematical model using COMSOL simulation software. A triple structure was obtained by comparison (d3=3d1=3d2=43\u00a0m, d3=3d1=3d2=43\u00a0m, \u03c61=0, \u03c62=4\u03c05\u00a0rad. \u03c63=\u03c0\u00a0rad), which can produce a strong characteristic magnetic signal similar to a heart-shaped field pattern. Finally, a signal transceiver system was set up for the experiment. The experimental result shows that the waveform of the magnetic signal generated by the real beacon meets the requirement of having a unique maximum value and good directivity within a period, which proves the practical application effect of the structure.<\/jats:p>","DOI":"10.3390\/s22218304","type":"journal-article","created":{"date-parts":[[2022,10,30]],"date-time":"2022-10-30T10:47:57Z","timestamp":1667126877000},"page":"8304","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Source Structure Design of the Rotating Magnetic Beacon Based on Phase-Shift Direction Finding System"],"prefix":"10.3390","volume":"22","author":[{"given":"Bo","family":"Li","sequence":"first","affiliation":[{"name":"Information and Navigation College, Air Force Engineer University, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Binfeng","family":"Yang","sequence":"additional","affiliation":[{"name":"Information and Navigation College, Air Force Engineer University, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fenghua","family":"Xiang","sequence":"additional","affiliation":[{"name":"Information and Navigation College, Air Force Engineer University, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiaojiao","family":"Guo","sequence":"additional","affiliation":[{"name":"Information and Navigation College, Air Force Engineer University, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hailin","family":"Li","sequence":"additional","affiliation":[{"name":"Information and Navigation College, Air Force Engineer University, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1088\/1755-1315\/237\/3\/032034","article-title":"Research on Magnetic localization method of underwater Magnetometer in Single component","volume":"237","author":"Zhu","year":"2019","journal-title":"IOP Conf.
