Effect of strong ocean currents on sound propagation is simulated numerically in framework of ray acoustics. For acoustic remote sensing of sound speed and flow velocity a nonperturbative approach is proposed and implemented. Under environmental conditions typical to the Gulf Stream applicability of this approach is demonstrated.L'influence du courant océanique fort à la propagation du son est reproduite numériquement par l'approximation de l'acoustique rayonnante. Pour le sentiment acoustique loing de la vitesse sonore et de la rapidité du flot l'approche nonperturbatrice est propos et réalisée. Sous les conditions de l'environnement typiques pour Gulf Stream l'applicabilité de cette approche est démontrée
