| 中文摘要: |
| 针对多数模拟器无法营造逼真操作感受的问题,提出了一种基于声呐实录音频的吊放声呐模拟器,并给出仿真实例。该系统运用反波束形成技术,基于实录音频合成具有真实听觉感受的阵元域信号,采用真实的波束形成方法和信号处理方法,能够得到与实际装备十分近似的视觉效果和听觉感受,对声呐操作员的日常训练是十分有益的。 |
| 英文摘要: |
| To resolve the problem that many sonar simulators lack a certain realistic feeling in operation, a dipping sonar simulator based on recorded audio is put forward, and simulation results are given. By using inverse beamforming technology, array signals which have a realistic feeling are produced with recorded audio in element domain. With the true beamforming and signal processing methods used in actual sonar, the simulator has a sense of realistic feeling in vision and hearing just like real equipment, which is profitable for sonar operators' training. |
