摘要: 针对全方位机动的潜艇目标,结合反潜直升机实际搜潜过程,分析了风因素对反潜机探测过程的影响;建立了反潜机吊放声纳的扩展螺旋线形应召搜潜模型、潜艇运动模型;依据声纳主被动探测距离模型,对主被动吊声的探测距离进行分析;仿真分析了在已知海洋环境条件下,反潜机扩展螺旋线形应召搜潜轨迹,不同发射频率和目标强度条件下的主被动吊声探测范围,以及比较分析了吊放声纳作用距离、潜艇运动样式等因素对文中提出的扩展螺旋线形搜潜方法与传统的扩展方形、扩展圆形搜潜方法的搜索概率影响.结果表明,扩展螺旋线形的搜潜效能优于扩展方形和扩展圆形.

Abstract: Based on the omnidirectional moving submarine targets, and the actual searching prcess of anti-submarine airplane, the wind factor affeacting searching prcess was analyzed. Extended spirality searching model of dipping sonar and submarine moving models were built. According to the models of active/passive dipping sonar, searching ranges of active/passive dipping sonar were discussed. In the factor of given ocean environment, experimental results simulated and analyzed the extended spirality searching course of dipping sonar, and searching ranges of dipping sonar for different target strengthesand emission frequency. The experimentation compared and analyzed the influence of the varieties of seaching range of dipping sonar, submarine moving manners on extended square, extended circle and extended spirality searching manners. The experimental results indicate that the search efficiency of extended spirality searching manner of dipping sonar is better than extended square and extended circle.
