In this paper, a RGPO mainlobe jamming suppression approach is proposed, with a frequency diverse array using multiple-input multiple-output (FDA-MIMO) radar. The RGPO mainlobe jamming differs from the true target in slant range, thus it is possible to identify the true target from the RGPO mainlobe jammings by exploiting the transmit beampattern diversity of FDA-MIMO radar. A RGPO mainlobe jamming suppression approach is devised by using joint transmit\u2013receive beamforming for a group of range sectors. The jamming suppression performance is studied, in consideration of practical time-delay of RGPO jamming. Simulation examples are provided to verify the effectiveness of the proposed approach.<\/jats:p>","DOI":"10.3390\/rs14061499","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:37:17Z","timestamp":1647812237000},"page":"1499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Range Gate Pull-Off Mainlobe Jamming Suppression Approach with FDA-MIMO Radar: Theoretical Formalism and Numerical Study"],"prefix":"10.3390","volume":"14","author":[{"given":"Pengfei","family":"Wan","sequence":"first","affiliation":[{"name":"National Lab of Radar Signal Processing, School of Electronic Engineering, Xidian University, Xi\u2019an 710071, China"},{"name":"Air and Missile Defence College, Air Force Engineering University, Xi\u2019an 710051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanlong","family":"Weng","sequence":"additional","affiliation":[{"name":"National Lab of Radar Signal Processing, School of Electronic Engineering, Xidian University, Xi\u2019an 710071, China"},{"name":"The 38th Research Institute of China Electronics Technology Group Corporation, Hefei 230088, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1865-6214","authenticated-orcid":false,"given":"Jingwei","family":"Xu","sequence":"additional","affiliation":[{"name":"National Lab of Radar Signal Processing, School of Electronic Engineering, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guisheng","family":"Liao","sequence":"additional","affiliation":[{"name":"National Lab of Radar Signal Processing, School of Electronic Engineering, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1109\/TGRS.2012.2199120","article-title":"MIMO Radar and Ground-Based SAR Imaging Systems: Equivalent Approaches for Remote Sensing","volume":"51","author":"Tarchi","year":"2012","journal-title":"IEEE Trans.
