中文摘要：
根据主动声纳浮标搜潜的工作过程，对潜艇规避对主动声纳浮标作战效能的影响进行了研究。建立了主动声纳浮标的数学检测模型。利用平滑平均声场理论推导了潜艇深度变化后浮标的探测范围，从检测概率和探测距离两个方面研究了潜艇采用不同规避航向、航深、以及海况对浮标作战效能的影响。仿真结果表明：在一定条件下，潜艇采用合适的规避策略，会显著降低主动声纳浮标的作战效能。
英文摘要：
According to the course of active sonobuoy searching submarine, the effects of submarine evasion on combat effectiveness of active sonobuoy is studied. The mathematical models of active sonobuoy detecting targets are established. According to the theory of smooth averaged sound field in shallow water, the searching scope of active sonobuoy is deduced when the depth of submarine is changed. Basing on the presented models, the searching scope and detection probability of active sonobuoy are estimated, and the effects of different evasion angles, depth and sea environment on searching submarine are amalyzed. Lastly simulation results show that under certain condition the combat effectiveness of active sonobuoy for submarine can be reduced by proper evasion strategy.
