沉底爆源大地坐标测量方法

沉底爆源大地坐标的定位测量是实船抗冲击试验的重点问题,对系统测量方案进行比较分析的基础上,通过数值仿真计算,对船载式短基线定位方案的测量精度进行了研究;海上验证试验表明：该方法使用方便、快捷,且通过合理控制测量阵位和多次重复测量,可达到对沉底目标高精度测量的要求。

Research on Geodetic Coordinates Measuring Method of Ground Explosion Source

The geodetic coordinates positioning of ground explosion source is an important issue in ship shock test. The paper first compares several methods of the measuring system, and then studies the positio- ning precision of shipped short baseline positioning system using numeric simulation. The validation trial shows its convenience and celerity and the measuring method can acquire high positioning precision by se- lecting rational measuring location and repeated measurements.
