摘要
常规声学立靶测量系统要求入射弹道垂直于预先设立的靶面,当弹道斜对靶面入射时,得到的计算结果误差较大。本文通过采用T型传感器布阵,提出了一种新的无风状态下弹丸斜入射时的数学模型。实验结果表明,该模型使斜入时定位精度得到了提高。
The conventional acoustic vertical target measuring system requires that the flying trajectory be vertical to the sensing screen. Otherwise the system will have large computation error. In this paper a new mathematical model of at oblique incidence based on the opened T-Shape target is put forward. By the model the experimental results show that the position accuracy is increased largely.
