摘要
本文介绍了一种基于实录噪声文件的实用声纳基阵信号测试系统。该系统基于海上实录的水声信号,结合特定的战术背景及声场环境,通过态势推演、声场计算、逆波束形成、插值等处理,实时产生符合精度要求的仿真声纳基阵信号以驱动声纳装备,实现在不同战术背景下的声纳岸上测试与操作训练功能。实践表明,该系统产生的信号具有高度的视觉和听觉逼真度。
In this paper, a sonar array signal simulation system is designed based on the WAV noise file. The system based on the real noise recorded on the sea, by considering of special tactic background and sound field, through a series of processing such as deducing manoeuver, inverse beamforming, sound field calculation, interpolation and so on, the sonar array signal needed for sonar equipment is generated, which achieve the on shore training in different tactic backgrounds. The training practice shows that the signal generated by this system is of good fidelity both in vision and hearing.
