According to the electric field and magnetic field integral equation, the electric and magnetic current were updated utilizing the Jacobi iteration method. Then, by introducing an expansion center lying in the neighborhood of the source point, Green\u2019s function was modified for near-field scattering between multiple hybrid dielectric and conductor targets. To accelerate the implementation of the procedure, the multilevel fast multipole method, the fast far-field approximation, and parallel multicore programming were introduced. Numerical results indicate that there is good agreement between the results calculated by the near-field IPO method and MLFMM solver in commercial software FEKO while significantly reducing the computational burden. To fully exploit the scattering information, the high resolution range profiles (HRRP) of different targets under different conditions were analyzed, which can be further applied for automatic target detection and recognition.<\/jats:p>","DOI":"10.3390\/rs15071884","type":"journal-article","created":{"date-parts":[[2023,3,31]],"date-time":"2023-03-31T14:19:33Z","timestamp":1680272373000},"page":"1884","source":"Crossref","is-referenced-by-count":1,"title":["Near-Field IPO for Analysis of EM Scattering from Multiple Hybrid Dielectric and Conductor Target and High Resolution Range Profiles"],"prefix":"10.3390","volume":"15","author":[{"given":"Qingkuan","family":"Wang","sequence":"first","affiliation":[{"name":"Air Defense and Antimissile School, Air Force Engineering University, Xi\u2019an 710051, China"}]},{"given":"Yijin","family":"Wang","sequence":"additional","affiliation":[{"name":"Air Defense and Antimissile School, Air Force Engineering University, Xi\u2019an 710051, China"}]},{"given":"Chuangming","family":"Tong","sequence":"additional","affiliation":[{"name":"Air Defense and Antimissile School, Air Force Engineering University, Xi\u2019an 710051, China"}]},{"given":"Zhaolong","family":"Wang","sequence":"additional","affiliation":[{"name":"Air Defense and Antimissile School, Air Force Engineering University, Xi\u2019an 710051, China"}]},{"given":"Ximin","family":"Li","sequence":"additional","affiliation":[{"name":"National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Tong","family":"Wang","sequence":"additional","affiliation":[{"name":"Air Defense and Antimissile School, Air Force Engineering University, Xi\u2019an 710051, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2820","DOI":"10.1109\/TAP.2020.3030914","article-title":"Scattering Prediction of Target Above Layered Rough Surface Based on Time-Domain Ray Tracing Modeling","volume":"69","author":"Wang","year":"2020","journal-title":"IEEE Trans.
