摘　　要：对高频图像声纳探测水雷的回波和声影进行计算机仿真。在OpenGL实现的三维场景中,建立三维空间中声纳波束仿真方案,给出了探测距离和回波强度两个关键问题的仿真算法,讨论了提高显示真实度的方法。软件实现结果表明,所给方法能正确仿真高频图像声纳的工作原理,准确表现声纳回波和声影图像,在理论研究、尤其是模拟训练领域具有重要应用价值。Sound reflection and sound shadow of high frequency imaging sonar detecting sea mine underwater was simulated with computer. A resolution for sonar beam simulation was arose in 3D space built with OpenGL, given calculation models for both the target range and level of sound reflection, and how to promote the reality of the simulation image. Application program manifests that the model simulates correctly the sonar＇s principle of sound reflection wave and sound shadow. The application is useful in theory research and simulation training especially.
