摘要
在双基地声呐系统中,发射站和接收站远距离分置,因此,双基地声呐在目标的检测、跟踪和定位等方面与单基地声呐相比差别很大。以接收站的观测信息为基础对目标进行二维定位,在数值仿真的基础上,分析了各参数的变化对系统定位精度的影响,为提高双基地声呐利用接收站信息对目标进行定位的精度提供了理论依据,在实际工程中有较强的应用价值。
The emitting station and the receiving station is separated distantly in the bistatic sonar system. Therefore, bistatic sonar systems have many special characters in target detection, tracking and localization compared with monostatic sonar. Target can be localized in two-dimension mode in the basic of the receiving station＇s measurements. The accuracy analysis for different parameters is given respectively through computer simulation. The research presents a theory basis for improving target＇s localization accuracy using the receiving station＇s measurements in bistatic sonar system. The proposed disposition scheme is available for real application.
