A quantitative assessment of the compatibility of Ultra Wideband with radiolocation services

In this coexistence study, the effect of an Ultra Wideband (UWB) MB-OFDM signal, as defined in the ECMA-368 standard, on an S-band radar device working in the 3.1 GHz to 3.4 GHz range is investigated. An extensive series of 6460 measurements, done with 20 different radar waveforms and for various radar and UWB signal levels is analyzed, using a laboratory test bed specifically designed for this purpose. The interfered radar signal is acquired by a spectrum analyzer and then processed on a stand-alone PC. Different post-processing techniques are applied, depending on the type of the selected radar receiver structure.
