摘要
构建了一个基于水声成像并针对水下尺度目标的半实物仿真系统。提出了仿真系统的功能需求,通过板块元算法建立了水下尺度目标空间声图像回波模型,设计了仿真系统的组成结构、硬件和软件等,研究了将模型应用于仿真系统的实时信号生成技术。水池试验结果证明仿真系统能够模拟Benchmark标准潜艇模型的水声成像回波信号,成像结果具有一定的可识别性,并能推广到任意水下目标的水声成像回波仿真,可满足水声成像系统研究的仿真需求。
A semi physical simulation system based on underwater scale target and acoustic imaging is designed. Functional requirements are presented, the echo models of underwater scale target acoustic image are established through the planar element method, the structure, hardware and software are designed, the real-time signal generation techniques of applying the model to the simulation system are researched. The results of underwater experiment show that the simulation system can simulate the acoustic imaging echo signal of Benchmark submarine model, the imaging results are recognizable to some extent, it can be promoted to any underwater scale target and meet the requirements of acoustic imaging system development.
