摘　　要：水声传播特性受海洋环境的水文条件影响严重,具有非常显著的时变和空变特性,直接制约着鱼雷自导性能。基于波束追踪(Bellhop)声场计算方法,综合考虑信道特性、装备自身特性和目标特性,建立鱼雷自导作用距离预估模型,提出鱼雷工作深度选择方法,可为鱼雷探测能力评估、作战规划、作战参数选择等提供技术手段。通过仿真和实航试验结果,分析水文环境对鱼雷自导作用距离的影响,验证了预估模型的准确性,研究成果可用于指导鱼雷作战使用,并为研究鱼雷自导环境适应性问题提供参考。The underwater acoustic propagation characteristics are seriously affected by the water conditions and have very significant time-varying and space-varying characteristic,which directly restricts the homing performance of torpedo.Based on the calculation method of beam tracking sound filed(BELLHOP) and considering the characteristic of channel,equipment and target,the torpedo homing range estimate model was established and the torpedo working depth selection method was proposed.The model and method can provide scientific method for torpedo detection capability evaluation,planned operation and operation parameter selection.The influence of water conditions on torpedo homing range was analyzed,and the results of simulation and sea trials illustrated the efficiency of the estimate model.The research results can be used to guide torpedo operation,and provide reference for studying the adaptability of torpedo homing environment.
