Definitions for "Spectral analysis"
study of the distribution by wavelength or frequency of the radiation emitted by an object of interest.
Study of a spectrum, so as to learn the detailed physical and chemical characteristics of the object which produced the light, and the gases through which the light passed, after leaving the object.
any signal such as gravity and magnetic data is composed of an infinite number of superimposed sine curves of various frequencies and amplitudes. Using Fourier methods, a spectrum of wavenumber versus amplitude can be produced. This has a variety of uses, such as assisting decisions on regional/residual separation, depth estimating and filter cut-off choices. back
the analysis of geological phenomena (vegetation, soil deposits, etc.) by interpreting the variation in color values from imagery
