目标和环境特性对被动声呐浮标探测范围的影响

被动声呐浮标的探测性能不仅和自身设备性能有关,还和目标运动特征及环境特性有着密切的关系。通过建立潜艇目标运动、海洋环境的数学模型,利用浅海平滑平均声场理论推导了潜艇深度变化后被动声呐浮标的探测范围,讨论了潜艇采用不同航速、航深以及海洋环境对被动声呐浮标探测范围的影响,并进行了仿真。结果表明,目标和环境特性对被动声呐浮标的探测范围有重要影响,这对航空反潜作战训练具有一定的指导意义。

The effect of target and environment character on detection scope of passive sonobuoy

The detection performance of passive sonobuoy is not only related to the equipment performance,but also connected with target and environment character.The models of submarine's motion and sea environment were first established,and according to the theory of smooth averaged sound field in shallow water,the searching scope of passive sonobuoy was deduced when submarine changed its evasion depth.The effects of different speeds,depth and sea environment on detection scope were discussed.Lastly simulations were made,and the results show that target and environment characters have an important effect on detection scope of passive sonobuoy,which is significant for aeronautical anti-submarine training.
