In this approach, the 2-way exact acoustic propagation path of the inclined array is transformed into the sum of a single root term and an offset term, where the single root term is the 2-way ideal propagation path and the offset term contains all errors cause by the inclined array. The correction for the offset term is separated into two steps: phase correction and delay correction. The phase correction is performed on the echo signal of each receiving hydrophone in the 2-D time domain by a phase multiplication and the delay correction is performed on the echo signal of each receiving hydrophone in the range frequency domain by a phase multiplication with a linear function of range frequency at the reference range. Finally, the effectiveness of the proposed approach is examined by the simulation experiments.<\/jats:p>","DOI":"10.3390\/s18072000","type":"journal-article","created":{"date-parts":[[2018,6,22]],"date-time":"2018-06-22T10:56:28Z","timestamp":1529664988000},"page":"2000","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Correction Approach for the Inclined Array of Hydrophones in Synthetic Aperture Sonar"],"prefix":"10.3390","volume":"18","author":[{"given":"Haoran","family":"Wu","sequence":"first","affiliation":[{"name":"Naval Institute of Underwater Acoustic Technology, Naval University of Engineering, Wuhan 430033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinsong","family":"Tang","sequence":"additional","affiliation":[{"name":"Naval Institute of Underwater Acoustic Technology, Naval University of Engineering, Wuhan 430033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heping","family":"Zhong","sequence":"additional","affiliation":[{"name":"Naval Institute of Underwater Acoustic Technology, Naval University of Engineering, Wuhan 430033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,22]]},"reference":[{"key":"ref_1","unstructured":"Marx, D., Nelson, M., Chang, E., Gillespie, W., Putney, A., and Warman, K.
