摘要
除自身性能外,吊放声纳的搜潜效果很大程度上会受到水文环境的影响,跃变层是夏季浅海经常出现的一种现象,且对声纳探测效果影响巨大。阐述了跃变层中的声传播特点,仿真了其声线传播的轨迹,分析了吊放声纳入水深度对其探测效果的影响。仿真分析表明同深探测可有效提升声纳探测效果。
The detection effects of dipping sonar are related not only to the equipment performance, but also to the environ-ment characteristics. Thermocline is a common phenomenon in the shallow sea during the summer, which has some great influ-ence on the sonar detection. In the paper, acoustic propagation characterestic of thermocline in the shallow sea are discussed, and then sound ray trace is simulated. The effect of the dipping sonar depth in water on the detection range is analyzed. The sim- ulation results show that keeping the sonar detector as deep as submarine can improve the performance of detection effects.
