The competition between the intrinsic motion of detonation and convected disturbance is analyzed computationally by both performing a dynamic mode decomposition analysis and obtaining the space-time correlations. The dynamic modes are considerably affected by the presence of pre-shock forcing, while the space-time correlations are weakly affected by the convected turbulence. The triple point motion dominates the space-time correlations and manifests itself with a shift of the ellipsis towards
