Abstract:
The article examines the possibility of simultaneous reconstruction of sources equivalent in the external field and spectral characteristics of the useful signal. Examples of variational formulations are given for various versions of the method of linear integral representations, and the problem is formulated of finding the distribution density of gravitating or magnetic masses on several horizontal planes and the Fourier transform of an anomalous field element from the values of a disturbed signal known at points of a certain observation network.
Key words:systems of linear algebraic equations, integral representations, Poisson summation formula.
