Abstract：Singular value decomposition method, a method for magnetotelluric sounding data processing, is recommended minutely; and its real number operation process is derived. For analysis, this method decomposes data matrix into signal matrix and noise matrix. It may give least squares estimation of response function, performs quantitative analysis of signal and noise to calculate S/N ratio, and offers the estimated variance of the response function. Theoretical calculation shows that this method is reliable and effective in suppressing noise, estimating response function, and analysingnoise and variance.
