Abstract
A signal processing method enabling reproduction of a broadband signal free of aliasing which transforms a plurality of discrete signals obtained by sampling an identical continuous signal using sampling phases different in a one-dimensional direction and containing a basic spectral component contained in the continuous signal and imaging components other than the basic spectral component to the frequency domain in a Fourier transforming circuit and shifts the phase in a spatial shift circuit, then solves predetermined simultaneous equations in a basic spectrum calculation circuit, finds complex numbers to be multiplied with the phase shifted plurality of signals, multiplying the calculated corresponding complex numbers with the plurality of signals, and adding the results of the multiplication to generate a signal free of the aliasing.
