摘　　要：针对训练弹水中弹道测量要求,提出水声测量和惯性测量2种方案。对水声测量的原理和应用范围进行分析,对惯性测量的工作原理、姿态矩阵解算、初始对准和误差补偿等方法进行研究。建立一套惯性测量系统并应用于试验,获取了相应的测量数据。Based on requirement for exit-water trajectory of missile,underwater sound measurement and inertial measurement were put forward. The principle and application scope were analysed. Meanwhile, the working principle, strap-down matrix solving algorithm, initial alignment, error compensation were studied. At last,the inertial measurement system wes developed and used in an experiment,the experiment data were acquired correctly.
