中文摘要：

反潜战中,被动定向声呐浮标是一种主要的探潜手段,两枚被动定向浮标同时发现目标即可对其进行定位。研究了初始浮标阵中仅有一枚浮标能够发现目标但不能实现定位的情况下,如何通过补投被动定向浮标对目标进行定位的模型问题。根据水下目标和反潜机的运动特点,将实际中所有可能出现的情况进行了分类讨论,建立了被动定向浮标的补投模型。通过仿真分析了模型的探测效能,验证了模型的正确性和可用性,为被动定向浮标的战术使用提供了一定的理论基础。

英文摘要：

In Anti-Submarine Warfare, passive directional sonar buoy is a main method to detect submarine. When two directional buoys have detected the same underwater target at the same time, its position could be fixed. A model about how to lay the supplementary passive directional buoys is researched to fix the position of underwater target in the condition that one and only one directional buoy in the original array has affirmed the existence of underwater target, but could not fix its position. According to the motion features of both underwater target and antisubmarine aircraft, sup-plementary dropping model of passive directional buoy is established in consideration that all possible situations may occur in practice. By simulation, the detection efficiency of the model is analyzed and the applicability is proved. All of these provide a theoretical foundation for tactical uses of passive directional buoys.
