Evaluation and Analysis of Linearity Measurement Uncertainty of Seismic Data Acquisition Device
Abstract This paper establishes the linearity models based on least squares method and terminal-based straight line method of seismic data acquisition device respectively. It analyzes the source and gives the calculation formula and the evaluation process of uncertainry. It compares and analyzes the differences between the least squares method and the terminal-based straight line method in the evaluation of linearity uncertainty and the influence of the number of input points on the evaluation of linearity uncertainty. The results show that the linearity uncertainty evaluation of the methods are on the same order of magnitude, and the terminal-based straight line method is less affected by the number of input points.
Key words :
