舰炮射击海上弹着点声学测量方法及精度仿真

Measuring Method of Ship-Borne Gun Shot Landing Point on Sea and Its Accuracy Simulation

针对舰炮射击弹着点的精确测量,提出了利用声传感器测量舰炮射击海上弹着点的方法,并建立了基本方程。对测量系统的原理和测量信息的传输方式进行了分析,在此基础上,对声传感器位置误差、测时误差及二者综合作用对测量精度的影响分别进行了仿真计算,证明测量原理可行,测量精度满足要求。

The method of measuring ship-borne gun shot landing point by using hydrophone has been put forward in this pa-per, and the basic equations have been also established. In addition, on the basis of the analysis on the principle of the measuring system and the transmission mode of the measuring information, the effects of location errors, time measuring er-rors and both the two errors together on the measuring accuracy have been simulating and calculating. The results show that the measuring principle is viable, and the measuring precision meets the challenge.
