The invention provides a diffraction wave imaging method, device and electronic equipment, the method comprises the following steps of: acquiring a co-imaging channel set in an angle domain; the co-imaging channel set comprises a plurality of imaging channels; each imaging track set corresponding to an imaging point; each imaging channel set comprising a plurality of sampling points; each samplingpoint comprises a time parameter; each imaging channel set is processed as follows: dividing the sampling points according to the time parameters to obtain a plurality of time slices, calculating theattenuation factor and the attenuation coefficient of each sampling point of each time slice, carrying out superposition calculation on the attenuation coefficients corresponding to a plurality of sampling points and a plurality of sampling points of each time slice to obtain the imaging result of each time slice, collecting the imaging results, obtaining the imaging result of each imaging point,and collecting the imaging result of each imaging point, thereby obtaining the imaging result of the co-imaging channel set. According to the invention, the reflected wave and noise are effectively suppressed, the diffraction wave is enhanced and the resolution of diffraction wave imaging results is improved.
