提出了一种同步工作方式下鱼雷实艇靶末弹道测量的线性、非线性算法,分析了测量误差,并进行了误差仿真,给出了误差分布曲线。仿真结果表明,基阵位置误差和时延测时误差对定位精度影响较大,测声速误差的影响较小,而系统的姿态修正误差对定位精度的影响不容忽视。
A linear and non-linear algorithm for target end-torpedo measurement of torpedo boat under synchronous working mode was proposed. The measurement error was analyzed and the error was simulated. The error distribution curve was given. The simulation results show that the position error of array and the time delay measurement error have a great influence on the positioning accuracy and the influence of the sound velocity error is small. The influence of the system attitude correction error on the positioning accuracy can not be ignored.
