摘要
简要说明了干涉仪合成孔径声纳基本原理和信号处理过程：合成孔径成像、干涉图获取与处理和相位解卷。介绍了我国首台干涉仪合成孔径声纳原理样机研制的基本情况，给出了该样机水池及湖试试验结果。试验结果表明：干涉仪合成孔径声纳兼备合成孔径声纳高分辨率和干涉测深精度高的优点；设计的原理样机是成功的。
InSAS basic principle and signal processing including SAS imaging, interferogram acquisition and processing, phase unwrapping are simply introduced. The first InSAS prototype in China is presented and its results from the trials in water tank and in lake are demonstrated respectively. The trial results indicate that InSAS combines the advantages of high resolution of SAS and high bathymetry precision. The InSAS prototype is proved successful.
