    Abstract
  • The ambiguity function of wideband pulse train signal is a powerful tool for signal analyzing and waveform designing, and a common method in detection and estimation. Realization of the ambiguity function firstly needs syn-thesizing replicas. However, directly copying scale extension of the sub pulse and multiplying different weights to syn-thesize replicas may cause most replicas vectors losing and information missing. In order to solve this problem, this paper adopts a new method for synthesizing replica signal, in which the entire pulse train is firstly compressed and then resampled. Simulation on the pulse train of linear frequency-modulated waveforms′ ambiguity function shows that the method is feasible and applicable to achieve ambiguity function of wideband pulse train signal.
