Abstract
声遥测水中悬浮粒子(如泥沙)的反向散射强度,可反演获得粒子浓度。可是,遥测系统对采样体积采集的声反向散射,除了粒子的散射信号外,还包含附加的干扰和噪声。本文探讨采集悬浮粒子声反向散射信号时,如何降低干扰源和噪声源对其影响的若干对策
 
The concentration of suspended particles in water can be estimated by inversion of the backscatter intensity with the acoustic telemetering system.Besides the backscattering signal From particles,however,the acoustic backscatter gathered From the sampled volume by the system also contains additional interFerence and noise.In this paper,it is discussed how to mitigate interFerence and noise which impair severely the eFFective backscattering signal From the particles.
