The invention relates to a scattered wave seismic advanced detection imaging method and device, a medium, electronic equipment and a product, and the method comprises the steps: obtaining seismic source data and seismic record data from a seismic advanced detection system; fourier transform is carried out on the seismic source data to obtain seismic source frequency wave number domain data, the seismic source frequency wave number domain data is used as an initial value condition, calculation of a forward continuation field is carried out, and forward scattering wave field signals are obtained; performing Fourier transform on the seismic record data to obtain seismic record frequency wavenumber domain data, and performing calculation of a reverse continuation field by taking the seismic record frequency wavenumber domain data as a boundary value condition to obtain a back propagation scattering wave field; and performing cross-correlation imaging on the forward scattering wave field signal and the backward sc
