Ultra-wideband (UWB) radio systems are gaining importance in the further development of high data rate communications. Besides widely implemented multiband transmission techniques, the direct pulsed mode of operation is still under research. It is appealing because of its high resolution in time domain (TD) and thus low interception and interference possibilities. In this paper the inverse discrete Radon transform (IDRT) technique for synthesis and transmission of the far-field pulsed beams in linear isotropic antenna arrays as well as the effects of pulse shape, array configuration and computation are investigated. The time-space beamforming is based on the a priori knowledge of the pulse chosen for binary signalling, the properties of which are inspected for adequate configuration setting. For a desired discretised time-space mask, the method solves for discrete time shapes of the individual source fields. Unlike previous iterative approaches the inversion problem of Radon transform (RT) was addressed here directly in the discrete domain. A verification of this procedure has been conducted using simulated data.
