The application of the noise of the underwater weapon launching measurement system based on power spectrum analysis

对水下发射噪声测量方法进行研究,研制一套符合近场测量方式的自容式宽动态范围水声信号测量存储设备。结合虚拟仪器技术特性,对基于虚拟仪器技术的发射噪声测量分析系统的总体结构和技术途径进行研究,并提出了解决方案。研究结果为后续水下声学测量装备研制、关键技术指标的选定和目标精确判读定位等提供强有力的技术支撑。

The study on the measurement method of the noise of the underwater weapon launching has been held on. A storage device of underwater acoustic signal was designed based on a self-contained and wide dynamic range. in this paper a measurement noise analysis system based on virtual instrument technology was studied,included its general structure and technical way,and the solution of the problem was put forward. The research results provided powerful technical support for the development of the subsequent underwater acoustic device,the selection of the key technical indexes and the recognition of the target,etc.
