基于液电效应的水下宽带干扰源研究

Study on Underwater Wideband Acoustic Interference Source Based on Electrohydraulic Effect

研究了液电效应的原理、产生结构和声辐射特性,介绍了压制型噪声干扰的工作原理,从干扰噪声级、噪声频率范围和持续工作时间三方面分析了液电效应的声辐射特性,研究表明液电效应可以作为压制型宽带噪声干扰源,应用于水声对抗。

The theory, production and acoustical characteristics of EHE（Electrohydraulic Effect） are analyzed, and the theory of noise jammer is discussed. In the way of interference source level, interference frequency range and duration of signal, the acoustical characteristics of electrohydraulic effect can be used in wideband acoustic interference of underwater countermeasure.
