This technique produces high-density false targets that resemble a comb shape after pulse compression processing, resulting in both deceiving and suppressing effects. In order to suppress jamming effectively, a new antijamming technique has been proposed that combines Lv\u2019s distribution (LVD) with biorthogonal Fourier transform (BFT). The main idea of this antijamming method is based on a three-step process: \u201cparameter estimation\u2014echo modulation\u2014identification and suppression.\u201d The first step involves obtaining the delay and chirp rate of the jamming from the LVD matrix of the radar echo. Based on the estimated parameter information, a reference signal is designed to modulate the jamming into a complete chirp signal. In the second step, biorthogonal Fourier transform is used to distinguish between the target\u2019s echo and jamming based on the difference in the chirp rate. Finally, jamming is filtered using narrow-band filtering in the chirp rate domain, and the original echo is recovered by using biorthogonal inverse Fourier transform (IBFT). Simulation results demonstrate that the proposed method achieves high accuracy in estimating jamming parameters and is capable of suppressing false targets under high jamming-to-signal ratio (JSR) conditions.<\/jats:p>","DOI":"10.1155\/2024\/7070078","type":"journal-article","created":{"date-parts":[[2024,1,23]],"date-time":"2024-01-23T03:35:08Z","timestamp":1705980908000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["Suppression Method for Smeared Spectrum Jamming Based on Lv\u2019s Distribution Combined with Biorthogonal Fourier Transform"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9270-7914","authenticated-orcid":true,"given":"Zhenming","family":"Wen","sequence":"first","affiliation":[{"name":"Institute of Information Fusion, Naval Aviation University, Yantai 264001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guohong","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Information Fusion, Naval Aviation University, Yantai 264001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongbo","family":"Yu","sequence":"additional","affiliation":[{"name":"Institute of Information Fusion, Naval Aviation University, Yantai 264001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"article-title":"ECM techniques to counter pulse compression radar","year":"2006","author":"J.
