Abstract
cause the resultant wavefield is band-limited, the oversampled wavefield within the receiving aperture can be extrapolated over to an extended region. Then the resolution of the images can be considerably imh(x) = - exp (i2nr/~) cos + proved due to the extension of the aperture after extrapolation. (jAr)1'2 - 1z exp (j2nr/X)
