基于双基阵的高炮弹丸炸点被动声定位研究

Study on Passive Acoustic Locating Shell Burst of Antiaircraft Gun Based on Dual Arrays

被动声定位技术在许多领域中有着广泛的应用,但定位精度低一直是影响其工程应用的关键问题之一.在研究单基阵被动声定位技术的基础上,提出了基于双基阵的被动声定位基本原理和方法,并对高炮弹丸炸点的被动声定位进行了仿真实验.仿真结果表明,采用双基阵对高炮弹丸炸点进行被动声定位,其精度有较大提高,克服了单基阵定位精度低的不足.此原理和方法同样适用于对其它三维空中目标进行被动声定位.

The passive acoustic locating technology is used widely in many fields. The lower locating accuracy is one of the key problems that always affect its application. In this paper, compared with the single array locating, the fundamental and method of the passive acoustic locating based on dual arrays are studied, and simulation experiment is done. The results of simulation show that the accuracy of passive acoustic locating system based on dual arrays for shell burst of antiaircraft gun is improved, and can also be applied to locating other targets in three -dimensional space.
