In this paper, a coherent integration method for wideband radar, i.e., variable-scale moving target detection (VSMTD), is proposed to resist range migration and Doppler broadening. On the one hand, subband decomposition can effectively integrate the energy of the extended target in range using variable-scale transformation, accomplished by modulating the filter bank. On the other hand, it increases the coherent integration time by mitigating the range migration in a sufficiently narrow subband. The discrete Fourier transform (DFT) modulated filter bank and the fast Fourier transform (FFT) algorithm are also used to achieve fast VSMTD implementation. Finally, the simulation results demonstrate the superior performance of the proposed VSMTD method.<\/jats:p>","DOI":"10.3390\/rs14133156","type":"journal-article","created":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T20:59:18Z","timestamp":1656968358000},"page":"3156","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Variable-Scale Coherent Integration Method for Moving Target Detection in Wideband Radar"],"prefix":"10.3390","volume":"14","author":[{"given":"Tingkun","family":"Lu","sequence":"first","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology, No. 109 Deya Road, Changsha 410073, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3404-5445","authenticated-orcid":false,"given":"Feng","family":"He","sequence":"additional","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology, No. 109 Deya Road, Changsha 410073, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5864-0647","authenticated-orcid":false,"given":"Lei","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology, No. 109 Deya Road, Changsha 410073, China"}]},{"given":"Manqing","family":"Wu","sequence":"additional","affiliation":[{"name":"China Electronics Technology Group Corporation, Beijing 100846, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,1]]},"reference":[{"key":"ref_1","first-page":"5647","article-title":"The Fundamental Trajectory Reconstruction Results of Ground Moving Target from Single-Channel CSAR Geometry","volume":"56","author":"Wang","year":"2018","journal-title":"IEEE Trans.
