Timing tracking of ultra-wideband, pulse which narrower than Ins is a difficult problem. In existing timing technology, the timing range is narrow, and due to noise or effect of timing jitter, the timing precision becomes low and the timing stability deteriorates. In this scheme, a state space model for this problem is established and a novel timing tracking loop based on particle filtering is proposed. This scheme uses particle filtering algorithm to estimate the timing error and control the timing pulse. Simulation and experimental results show that the proposed method which utilizes the nonlinear processing ability of particle filtering has higher tracking precision and wider timing range compared with traditional digital timing loop.
