二元矢量阵混响实验设备研究
|
摘要
混响伴随发射信号产生是主动声纳系统主要的背景干扰,尤其是近程混响,大大限制了声纳的作用距离和参数估计性能。一般情况下,近程混响很难采集,因此对混响数据采集实验装置进行研究有着重大的意义。
本论文的主要工作是根据混响实验的需要,设计一套适用于二元矢量阵的混响数据采集测量实验装置,包括水声功率发射机的设计与调试;多通道数据采集系统设计与调试两部分内容。
水声信号功率发射机由信号源模块、数字信号处理模块、功率放大模块、电源模块和匹配网络五部分组成。本文从基本理论出发,结合现代音响功放的设计原理和经验,将集成化的数字音频功率放大技术应用到水声发射机的设计当中,从而有效的简化了水声功率发射机的设计难度,同时也降低了设计的成本。
多通道混响数据采集系统主要由电源板、模拟接收板和采集控制板组成,能够实现对混响信号的接收、放大、滤波和采集上传等功能。该系统通过220V交流电源供电,采用低噪声、低功耗、宽频带、大动态范围设计,能够实现信号的实时显示和自动增益控制等功能。本文还结合了混响信号的自身特点,采用了独特的抗饱和控制电路设计,能有效的解决信号采集过程中产生的采集器信号阻塞的问题。
Reverberation, especially short range reverberation which occurs after emission signal, is primary interference for the active sonar, consumedly limits the operation distance and parameter estimate of the active sonar, but sometimes the short range reverberation is difficult to collect. So it is necessary to design the Reverberation Data Acquisition System to collect the reverberation signal.
The main task of this paper is based on the needs of the reverberation experiment in designing a suitable binary vector array reverberation data acquisition measurements experimental apparatus, which includes the two parts of underwater acoustic power transmitter design and debugging and multi-channel data acquisition system design and commissioning.
Underwater acoustic signal power transmitter is composed of five parts: the signal source modules, digital signal processing, power amplifier module, power modules and matching networks. This paper researches the basic theory. It combines the designing principles and experience of modern audio power amplifier. It applies the digital audio power amplifier technology to the design of underwater acoustic transmitter, which will effectively simplify the designing difficulty and reducing the designing costs of underwater acoustic transmitter power.
Multi-channel reverberation data acquisition system is mainly composed of power board, analog receiver boards and control board. It can put the functions like mixed-signal receiving, zooming, filtering, collecting and uploading into practice. The equipment can be powered by 220-volt AC power supply, it adopts low-power, low-noise, wide band and wide dynamic range design, which is able to achieve real-time signal display and functions such as automatic gain control. This paper also combines the inherent characteristics of the reverberation signal. It adopts a unique anti-saturation control circuit design, which is effective to solve the problem of collector signal blocking in signal acquisition process.
