| 摘 要： | 在完成了轨道式干涉合成孔径声呐(InSAS)原理样机的基础上,研制开发了一种新型的水面拖曳式干涉合成孔径声呐系统。成像算法采用非停走停运动误差补偿的多子阵逐线算法。试验数据表明该系统稳定可靠,并成功获取了干涉合成孔径图像,其距离和方位分辨率分别达到了5 cm和10 cm,测深精度优于国际海道测量组织(IHO)标准。

| Abstract: | To verify the feasibility of Interferometric Synthetic Aperture Sonar (InSAS) in free tow mode other than rail mode, an experimental InSAS system has been developed, and a set of experimentations has also been conducted. The primary purpose of the experimentation is to confirm the validity of the image formation algorithm of multi-subarray synthetic aperture sonar proposed by us, platform and the phase unwrapping algorithms. An interferometic synthetic aperture image is successfully formatted by experimental results, and clearly shows the effectiveness of the InSAS system. It also shows the resolution ability of 5 cm and 10 cm in range and in azimuth respectively. The accuracy of bathymetry is better than International Hydrographic Organization (IHO) standard. |
