高精度测深侧扫系统在载人潜水器中的应用

为提升"蛟龙号"载人潜水器海底综合探测能力,介绍一种采用多子阵海底自动检测—子空间拟合的信号参数估计技术的高精度测深侧扫声纳系统。该系统安装于载人潜水器的两侧,能够测量海底的微地形地貌以及海底和水中的目标,同时获得探测区域高分辨率的地形图和地貌图。通过介绍该高精度测深侧扫系统的工作原理、技术指标及系统组成,结合"蛟龙号"载人潜水器试验性应用航次获得的高分辨率地形地貌数据,对该系统在载人潜水器中的应用和海底地形地貌探测结果进行了分析和展望。

The Application of High Resolution Bathymetric Sidescan Sonar System in Manned Submersible

To enhance the comprehensive exploration capability of the JiaoLong manned submersible,the paper introduces a High Resolution Bathymetric Sidescan Sonar System (HRBSSS),which is based upon multiple subarray auto bottom detection-subspace fitting signal parameter estimation processing method.The system is installed on both sides of the manned submersible,it can measure the microtopography of the seafloor,as well as the targets in sea and water,and obtain high-resolution topographical maps and geomorphological maps of the detection region.Through introducing introduces the working principle,technical parameters,hardware composition and software operation of the HRBSSS,combined with the high resolution topography data obtained by JiaoLong manned submersible experimental application voyage,the underwater topography detection results and the application of the system in manned submersible are analyzed.
