In this paper, an anti-ISRJ method based on the intra-pulse orthogonal waveform is proposed, which can recognize common interference signals by comparing sub-signal matched filtering results. For some special scenes where real targets cannot be directly differentiated from false targets, a new recognition method based on the energy discontinuity of the interference signal in the time domain is proposed in this paper. The method proposed in this paper can recognize real and false targets in all ISRJ modes without any prior information, such as jammer parameters, with a small amount of calculation, which is suitable for actual radar systems. Simulation experiments using different interference parameters show that although this method has a 3 dB loss of pulse compression gain, it can completely suppress different kinds of ISRJ interference when the SNR before pulse compression is higher than \u221220 dB, with 100% target detection probability.<\/jats:p>","DOI":"10.3390\/rs15143673","type":"journal-article","created":{"date-parts":[[2023,7,24]],"date-time":"2023-07-24T01:12:28Z","timestamp":1690161148000},"page":"3673","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Research on an Intra-Pulse Orthogonal Waveform and Methods Resisting Interrupted-Sampling Repeater Jamming within the Same Frequency Band"],"prefix":"10.3390","volume":"15","author":[{"given":"Huahua","family":"Dai","sequence":"first","affiliation":[{"name":"The College of Electronic Science and Technology, National University of Defense Technology, Changsha 410073, China"}]},{"given":"Yingxiao","family":"Zhao","sequence":"additional","affiliation":[{"name":"Information Research Center of Military Science, Academy of Military Sciences, Beijing 100142, China"}]},{"given":"Hanning","family":"Su","sequence":"additional","affiliation":[{"name":"The College of Electronic Science and Technology, National University of Defense Technology, Changsha 410073, China"}]},{"given":"Zhuang","family":"Wang","sequence":"additional","affiliation":[{"name":"The College of Electronic Science and Technology, National University of Defense Technology, Changsha 410073, China"}]},{"given":"Qinglong","family":"Bao","sequence":"additional","affiliation":[{"name":"The College of Electronic Science and Technology, National University of Defense Technology, Changsha 410073, China"}]},{"given":"Jiameng","family":"Pan","sequence":"additional","affiliation":[{"name":"The College of Electronic Science and Technology, National University of Defense Technology, Changsha 410073, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1007\/s11432-007-2017-y","article-title":"Mathematic principles of interrupted-sampling repeater jamming (ISRJ)","volume":"50","author":"Wang","year":"2007","journal-title":"Sci.
