摘要
根据主/被动联合多基地航空搜潜中主动声源、目标、被动接收器之间的空间几何位置关系,建立了目标位置的数学模型,确立了目标空间位置与主动声源-被动接收器声传播时间、主动声源-目标-被动接收器声传播时间、浮标方位角之间的关系;在此基础上,建立了各参量测量误差对目标定位误差影响的数学模型;最后,对所建定位及误差模型进行了仿真分析.
According to the space geometry site relationship of active sonar, target and passive buoys in combine multi-base aviation searching submarine, the target location mathematical model which related with the sound transmission time from active sonar to passive buoys is established. The sound transmission times from active sonar to target to passive buoys and the azimuth angle of passive buoys are determined. Based on the mathematic model, the orientation error models which caused by time measurement error and azimuth measurement error are given. Finally, the location and error models are simulated and analysed.
