By means of frequency-shifting jamming processing of the target echo signal and pulse compression during image processing, a group of false targets will appear in different spatial locations around the true target. Extracting the features of these false targets is complex and limited to existing countering methods against ISRJ. This paper proposes an anti-jamming method to identify the spatial location characteristics of two-dimensional deception false targets. By adjusting the parameters of the radar transmitted signal, the method simultaneously transmits the anti-jamming signal and carries out false target identification and elimination in the range and azimuth dimensions. Eventually, the optimal signal parameter design of the anti-jamming signal is obtained by comparing different anti-jamming strategies in the range dimension. The validity of the proposed method is proved by deducing the mathematical model between the spatial distribution characteristics of the false targets and the radar transmitted signal parameters and demonstrated by simulations.<\/jats:p>","DOI":"10.3390\/s21227702","type":"journal-article","created":{"date-parts":[[2021,11,19]],"date-time":"2021-11-19T08:29:17Z","timestamp":1637310557000},"page":"7702","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["An Anti-Jamming Method against Two-Dimensional Deception Jamming by Spatial Location Feature Recognition"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0453-2621","authenticated-orcid":false,"given":"Zhidong","family":"Liu","sequence":"first","affiliation":[{"name":"The Institute of Information and Navigation, Air Force Engineering University, Xi\u2019an 710077, China"},{"name":"The Collaborative Innovation Center of Information Sensing and Understanding, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qun","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Institute of Information and Navigation, Air Force Engineering University, Xi\u2019an 710077, China"},{"name":"The Collaborative Innovation Center of Information Sensing and Understanding, Xi\u2019an 710077, China"},{"name":"The Key Laboratory for Information Science of Electromagnetic Waves, Fudan University, Shanghai 200433, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaiming","family":"Li","sequence":"additional","affiliation":[{"name":"The Institute of Information and Navigation, Air Force Engineering University, Xi\u2019an 710077, China"},{"name":"The Collaborative Innovation Center of Information Sensing and Understanding, Xi\u2019an 710077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5870","DOI":"10.1109\/JSEN.2015.2453163","article-title":"An improved digital false-target image synthesizer method for countering inverse synthetic aperture radar","volume":"15","author":"Xu","year":"2015","journal-title":"IEEE Sens.
