چکیده انگلیسی
A theoretical arrival-time model with femtosecond precision is proposed. The model samples a laser pulse, then delays the discrete pulse sequence precisely. By reconstructing the delayed sequence we obtain the laser pulse in the analog domain with desired arrival-time. The kernel of the model is a filter bank, which is a cascade of digital unit delay filters, followed by a fractional delay filter. Furthermore, physical parameters such as the turbulence structure parameter, mean refractive index, turbulence outer scale and path-length along the propagating path are incorporated in the kernel. At last, through numerical examples, the femtosecond precision is manifested.
