Sustainable model for high signal to noise ratio to measure underwater acoustic signal using Acoustic Doppler Velocimeter

摘要

The objective of this research is to identify the optimum region in the underwater of flume, an artificial channel setup, to measure the acoustic signal. Acquiring the signal with high Signal to Noise Ratio is essential. Utilizing the Response Surface Methodology (RSM) with three factors Central Composite Design (CCD), this paper demonstrates the sustainable model of characterizing the Signal to Noise Ratio (SNR) through second order quadratic model in measuring the acoustic signal through Acoustic Doppler Velocimeter (ADV). Over all model fitness test of the suggested Design is justified by Degrees of freedom (DF). Highly Influenceable parameters of Signal to Noise Ratio are recognized using Analysis of Variance (ANOVA). The design for optimum region to investigate and acquire the signal for processing is acknowledged through F-Statistics. The multicolinearity of parameters is studied by Variance Inflation Factor, brought uncontrolled parameter such as Signal to Noise Ratio and Velocity of the measured signal to under control.
