双基地航空搜潜建模与仿真

根据双基地航空搜潜的特点,在对双基地条件下航空搜潜的搜潜距离及误差、目标强度、传播损失等模型及估算方法进行研究的基础上,建立了双基地航空搜潜条件下的搜潜距离和搜潜范围模型,确定了有效搜潜范围与发射声源级、环境噪声、接收指向性指数、检测阈值、声源与接收器的相对距离、目标方位等的关系,仿真分析了发射频率、双基地之间距离对搜潜距离和搜潜范围的影响,测向角对搜潜范围的影响等,获得了有益的结果,为航空搜潜训练提供了理论依据.

Modeling and Simulation for Bi-Static Aviation Searching Submarine

According to the features of bi-static aviation anti-submarine, the models and estimation method for searching distance, target strength and propagation loss of bi-static aviation searching submarine were studied. The searching distance and searching scope models established the relation among the transmitting source level, ambient noise, receiving direction index, detection threshold, relative distance between active sound source and buoy, and the target bearing etc. Some simulation tests analyzed the influence of transmitting frequency on the searching distance, the influence of distance between active source and buoy on the searching distance and searching scope, and the influence of bearing angle between the sound source to buoy and submarine to buoy on the searching scope. The results show that the models can get perfect effect and provide theoretic foundation for aviation anti-submarine training.
