摘要
以声呐探鱼器为参考,对超声波发生、接收、显示进行改进设计。束级高频声呐技术探测回波经处理后能最终在人机界面上形成探测目标平面轮廓和坐标等数据,利用其实现水下目标的准确判断。选用50、200kHz的高频超声波声呐进行了水面物体的探测实验,结合实验结果和人体特性给出设计改装方案。
Research and design were conducted on ultrasound generation,reception and display,with the reference to similar functions from sonar fish finder.Beam class sonar technology was used to develop the search and rescue equipment,which will produce datum including targets' one-dimensional contour as well as coordinates on human-machine interface,achieving accurate underwater targets location.Experiments of objects detecting were carried out using 50 kHZ and 200 kHZ ultrasound sonar,the relatively developed design ideas for modification were put forward combining the experiments results and human body characteristics.
