摘要
合成孔径声呐是一种高分辨率水下成像技术。该技术是基于小孔径基阵及其运动形成等效的大孔径,通过合成的大孔径波束形成过程,实现高分辨率成像。文章介绍了合成孔径声呐原理、特点、科学技术问题以及发展过程,分析了国内外合成孔径声呐研究的最新进展情况,并展望了合成孔径声呐的发展趋势。
Synthetic aperture sonar(SAS) is a technique of high resolution underwater imaging. Synthetic large aperture is formed based on small aperture array and its motion, and high resolution image is hence obtained by means of beam forming for large aperture array.Principle, characteristics, problem and history of SAS are presented in the paper. Recent developments and trend are analyzed as well.
