Design and Realization of the Real Time Gathering and Display System EchoViewer of Super Broad-Band Sea-Bottom Profile Instrument

超宽频海底剖面仪实时采集显示系统EchoViewer是为新研制的超宽频海底剖面仪开发的配套软件。该软件从超宽频海底剖面仪的超宽频率和多频段分频合成的特点出发,同时兼容同类系统的需求进行设计,根据声纳在海底介质中的传播特点实现TVG算法和海底跟踪算法,结合遥感图像处理方法实现分频合成算法,并采用软件工程的管理方法实现整个系统的开发,具有系统控制、导航定位、数据采集并成图显示、数据回放和数据后处理等功能。该软件在超宽频海底剖面仪多次海试和国家海洋局908浅剖专项调查任务中得到成功应用。

The real time gathering and display system, EchoViewer, is designed for the super broad-band sea-bottom profile instrument. The characteristic of super broad-band and multi-frequency synthe-sizing, as well as the compatibility with other system, have been considered during the software design. The TVG arithmetic and the seabed track arithmetic have been achieved according to the characteristic of propagation of the sonic wave in seabed. The multi-frequency synthesization has been realized by combining the remote sensing image processing technique. The abilities of system control, data gathering, GPS navigation, map display and data playback and process of the system have been demonstrated by the successful application in many tests and the survey of 908 project.
