- 摘要:
- 航空声呐浮标依靠水下声系统采集水下目标辐射噪声或者发射声脉冲并接收回波信号，实现探测功能。通过分析水下声系统运动的物理模型，将运动过程分为加速运动、匀速运动和减速运动等3个阶段，分别建立运动方程，求出各阶段的速度函数或位移函数。对相关参数赋值，得出相应曲线和水中释放时间。根据分析的方法和结论，进一步地研究更多类型航空声呐浮标水中释放过程，为反潜作战部署提供理论支撑。
By means of underwater acoustic system, airborne sonobuoy realizes the detection function via collecting the radiated noise of underwater target or by transmitting sound pulse and receiving echo signal of underwater target. By analyzing the physical model of underwater acoustic system motion, the motion process is divided into three stages: accelerated motion, uniform motion and deceleration motion. The motion equations are established respectively, and the velocity function or displacement function of each stage is obtained. Assign values to relevant parameters, and get the corresponding curves and deployment time. According to the methods and conclusions provided, the deployment process of more airborne sonobuoys can be further studied, providing theoretical support for anti-submarine warfare.
