| 中文摘要: |
| 介绍了干涉合成孔径声纳海试样机的研制情况,重点阐述了其中的主要关键技术:实时干涉信号处理技术、高稳定性拖曳体设计以及高幅相一致性基阵设计,并给出了干涉合成孔径声纳的湖试和海试成像结果。结果表明:干涉合成孔径声纳海试样机系统稳定可靠,成功获取了海底的高精度数字高程图,距离分辨率达到2.5cm,方位分辨率达到5cm,高程测量精度约为0.15m。 |
| 英文摘要: |
| A prototype of Interferometric Synthetic Aperture Sonar(InSAS) for sea trial has been developed.The key techniques are described in detail,which include real-time interferometric signal processing,design of high-stable tow-fish and design of the hydrophone array with high amplitude-phase uniformity.The testing results in lake trial and sea trial show that the InSAS testing system is stable and robust for acquiring the precise Digital Elevation Model(DEM) of seabed with a resolution of 2.5 cm in across direction and 5 cm in along direction,respectively.And the measuring precision of DEM is about 15 cm. |
