Pulse Amplitude Modulation Direct Sequence Ultra Wideband Sharing Signal for Communication and Radar Systems

Applying to inter-vehicle communication and satellite communication and location among satellite formation, the sharing signal of integrated systems that applied with ultra wideband (UWB) signal was presented. Pulse amplitude modulation direct sequence ultra wideband (PAM DS UWB) sharing signal model was given, and its power spectrum density was introduced. The ambiguity function of PAM DS UWB sharing signal was derived. From numerical simulations, the PAM DS UWB sharing signal yielded the so-called thumbtack ambiguity function. For practical application, the discussion about estimating communication link and radar range was carried out. The relations among five parameters of the sharing signal were analyzed, too. The results show that the PAM DS UWB signal can be applied to integrated systems.
