摘要：
This paper discusses the conditions which an active wideband echo model in the active echo location should satisfies in a strict sense. Then the analysis of wideband signal's velocity and distance resolutions is proposed. It is proved that the duration and the carrier frequency of the transmitted signal determine resolutions. Finally, the cosine signal with Gauss envelope is analyzed by the method proposed and some results are given. The work above provides an efficient analyzing tool for the wideband signal processing.
