【Abstract】 The requirements of ocean development and anti-submarine warfare is the main motivation of sonar technology study. The theoretical development and achievements in the area of underwater acoustic physics and underwater acoustic engineering make sonar system more and more complete. The opportunities and the challenges facing sonar technology in 21st century is described in this article. The hot topics of underwater acoustic signal processing and the innovation problems in sonar system design are also discussed.更多还原
