In this way , echo measure instrument be given birth , moreover it be adopted in generally now 这样，回声测深仪就诞生，现已为船只普遍采用。
Multibeam echo sounder system is a kind of sea bed surveying instruments which can work efficiently and accurately its development originally bases on single beam echo sounder this kind of system is very suitable for massive sea floor surveying the technique behind multibeam echo sounder system has achieved its maturity with time passage 多波束测深系统是一种具有高效的、高测量精度的用于海底地形测绘的设备，它是在回声测深仪的基础上发展起来的，特别适合于大面积的扫海测量工作。
To get the stability of shallow structure foundation and adjacent seabed in cheng dao shallow sea area , we have made an investigation on high resolution echo depth side sonar and shallow strata section etc . and made use of experiment analysis of core , in situ , indoor to compute , analyze and assess the stability on new computing method 为了得到埕岛海域浅水区构筑物地基及周边底床稳定性，本文通过高分辨率的回声测深、旁侧声纳及浅地层剖面等声学仪器勘查，并结合钻孔、现场和室内的实验分析，采用新的计算方法，对埕岛海域浅水区人工构筑物地基及周边底床稳定性进行了计算、分析和评价。
