通过建立反潜机的方形、扇形和螺旋线形应召搜索模型,分析讨论了潜艇航速和航向的变化对吊放声纳搜索概率的影响,并进行了仿真比较。结果表明,随着潜艇航速、航向角度的增加,吊放声纳搜索概率不断下降,且航速、航向变化对螺旋线形搜索的搜潜概率影响要小于方形搜索和扇形搜索。同时也表明潜艇以远离当前吊放点为规避航向且全速规避时会明显降低吊放声纳的搜索概率,这对潜艇规避对抗吊放声纳搜索具有实际的指导意义。
By setting up square, fan-shaped and helix-shaped search models of antisubmarine aircraft, the influence of submarine speed and course change on the search probability of suspended sonar is analyzed and compared. The results show that with the increase of submarine speed and course angle, the probability of searching for the suspended sonar decreases continuously. And the change of speed and heading has less effect on the search potential of spiral-shaped search than that of square search and sector search. At the same time, it also shows that the search probability of the submarine will be significantly reduced when the submarine moves away from the current point to avoid the heading and evade at full speed. This is a practical guide for the submarine to avoid the search of the sonar search.
