Abstract :
A novel sampling and recovering method based on step-delay pulses (SDP) for impulse radio ultra-wideband (IR-UWB) radar signal is presented in this paper. The SDP is used as the transmitted pulses of radar and the echoes from one group of SDP is used to reconstruct one pulse signal according to pulse delay relationship at the receiver. The SDP method is equivalent to increase the sampling rate and improve the performance of the reconstructing signal. Simulation results and discussion are given to evaluate the performance of the new approach. Related experiment are presented to demonstrate the theoretical feasibility of new method in signal sampling and recovering. The results show that the proposed method can sample and reconstruct IR-UWB signal and increase S NR effectively.
