摘要
为使三维成像声纳数据采集系统的设计达到周期短、可靠性高、满足性能指标要求的目标,提出一种改进的设计方法。该方法通过分析声纳设计指标及工作时的信号、噪声过程,提出采集系统的三个主要设计参数:TVG动态范围、最高增益及最高等效输入噪声所满足的约束方程。通过求解约束方程,获得采集系统设计参数需要满足的最低要求,以此为指导设计的数据采集系统满足声呐设计要求。通过原型设计的多次湖试实验验证了该设计方法切实有效。
In order to shorten the design period and improve the reliability of the 3D imaging sonar data acquisition system,and meet the requirements of performance index,an improved design method is proposed.By analyzing the design index of sonar,and signal process and noise process for working sonar,three main design parameters of the acquisition system are proposed,including the TVG dynamic range,maximum gain and maximum equivalent input noise satisfying the constraint equations.The constraint equations are solved to get the minimum requirements satisfying the design parameters of the data acquisition system.The data acquisition system meets the requirement of sonar design.The many lake tests of prototype design were performed to verify the efficiency of the designed method.
