Abstract :
In this correspondence, we prove that the Radon transform of the cross Wigner distribution function is a separable multiplication of fractional Fourier transforms of these functions. Thus, the 2-D cross ambiguity function is a surface of fractional correlation for 1-D signals, each associated with the angle of observation over the surface
