摘　　要：针对目前航空吊放声纳在实际工作中布放深度的选择主要依靠声纳员经验的现状,论文基于Argo浮标在北纬21.058°,东经118.971°附近海域10个月的实测温深数据展开分析。首先,利用威尔逊公式计算出该海域的声速剖面数据,并对其结构和统计特性进行了分析;然后,结合BELLHOP模型计算了其传播损失图,研究了该海域航空吊放声纳的作用距离特点,为吊放声纳的使用提供参考。For the current situation of the selection of depth of the dipping sonar is mainly relies on the experience of the sonar operator.The actual temperature ande depth datas of Argo buoys in the sea area near 21.058°north latitude and 118.971°east longitude for 10 months are analyzed.Firstly,the sound velocity profile datas of the sea area is caculated using Wilson's formula,and its structural and statistical properties are analyzed.Then,the propagation loss plot is calculated combining with the BELLHOP model,the operating distance characteristics of aerial dipping sonar in thie sea area are studied,which provides a reference for the combat use of dipping sonar.
