Influence of array elements’ consistency on SNR of hydrophone array
Journal of Measurement Science and Instrumentation, 2019 The influence of array element’s consistency on the hydrophone array’s signal-to-noise ratio（SNR） is studied. The consistency of array elements means the outputs of all the array’s elements are the same, that is to say, the outputs have the same phase ...

The Area Signal-to-Noise Ratio: A Robust Alternative to Peak-Based SNR in Spectroscopic Analysis
In spectroscopic analysis, the peak-based signal-to-noise ratio (pSNR) is commonly used but suffers from limitations such as sensitivity to noise spikes and reduced effectiveness for broader peaks. We introduce the area-based signal-to-noise ratio (aSNR) as a robust alternative that integrates the signal over a defined region of interest, reducing ...
