相关测速声呐海底回波仿真系统设计

相关测速声呐通过对回波数据的空间相关函数与空间相关函数理论公式进行模型匹配来获得载体速度等信息。回波空间相关函数的主瓣宽度影响载体的速度估计及精度。因此对海底回波空间相关函数特性的研究就显得尤为重要。依据相关测速声呐的工作特点,提出了采用Model-View-Controller(MVC)模式构建相关测速声呐海底回波仿真系统的设计方法,并基于VC 6.0软件开发平台将其实现。建立了友好的系统可视化仿真界面,为回波空间相关函数特性的研究提供了便利的平台。

The simulation design of sea-bottom backscattering for correlation velocity log system

The correlation sonar for velocity measurements （i.e. the correlation velocity log system） obtains the velocity of vessel and other information by using model-matching of the correlation function of echo data with the theoretical correlation function. The main lobe width of the spatial correlation of sea-bottom backscattering influences the accuracy of the vessel velocity estimation. Therefore, it is greatly important to research the spatial correlation of sea-bottom backscattering for correlation sonar. Based on the characteristics of correlation sonar, the MVC design pattern is pro-posed to build the simulation system of sea-bottom backscattering for correlation sonar, and the simulation software is implemented on the VC 6.0 software development platform. Establishing a friendly system of visual communication interface, the simulation software provides a convenient platform for the research on bottom reverberation simulation.
