被动全向浮标HYFIX定位精度仿真分析

Simulation Analysis on HYFIX Locating Accuracy of Passive Omnidirectional Sonobuoy

在HYFIX定位原理的基础上,建立了被动全向浮标HYFIX定位误差模型,通过计算机仿真分析了声纳作用距离、浮标布放间隔以及浮标布放阵形对被动全向浮标HYFIX定位精度的影响,为反潜机执行搜潜作战任务时,合理地选择浮标的布放间隔和布放阵形提供理论依据。

Based on the principle of hyperbolic fixing（HYFIX） , some mathematical models are set up for the HYFIX of passive omnidirectional sonobuoy. Through computer programming and simulating, the author analyzed the action range of the sonobuoy, the deployment space between sonobuoys and the effect of sonobuoy deployment array on locating accuracy from HYFIX of passive omnidirectional sonobuoy. It may provide a theoretical basis for choosing the appropriate space and array of sonobuoy deployment when the anti-submarine airplane carries out a submarine searching task.
