第一讲 进入21世纪的声纳技术

Sonar Technology of 21st Century

海洋开发和反潜战的需求是推动声纳技术开发的巨大动力.水声物理、水声信号处理及相关学科的发展又促使声纳设计日趋完善.文章介绍了声纳技术在进入21世纪时所面临的机遇和挑战,水声信号处理领域近期研究的热点问题以及声纳系统设计中的技术创新课题.

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.
