  The precise reconstruction of the turbulent volume is a key point in the
development of new-generation Adaptive Optics systems. We propose a new Cn2
profilometry method named CO-SLIDAR (COupled Slope and scIntillation Detection
And Ranging), that uses correlations of slopes and scintillation indexes
recorded on a Shack-Hartmann from two separated stars. CO-SLIDAR leads to an
accurate Cn2 retrieval for both low and high altitude layers. Here, we present
an end-to-end simulation of the Cn2 profile measurement. Two Shack-Hartmann
geometries are considered. The detection noises are taken into account and a
method to subtract the bias is proposed. Results are compared to Cn2 profiles
obtained from correlations of slopes only or correlations of scintillation
indexes only.
