摘要
介绍了一种检测智能型鱼雷的高性能扫频干扰标准声源的制作思路 ,给出了原理框图 ,对扫频信号的产生、均衡、放大 ,以及与换能器的匹配进行了阐述 ,并给出了具体的测量结果。从测量结果看出 ,该扫频干扰声源在较宽的工作频带内具有良好的幅频特性和较大的线性动态范围 ,能够满足很多具体的应用 。
The article introduces a good-performance design of a normal disturbing sound source to detect intelligent-model torpedoes. It presents the principle frame diagram, discusses the occurrence, equalization, amplification of the frequency sweep signal and the match of transducer, and presents the material measured results. From the measured results we can conclude that the frequency sweep disturbing sound source has favorable amplitude and frequent characteristic and larger linear dynamic range, and it could satisfy a great many material applications and has highly practical worthiness.
