A signal model and uniform circular antenna array model of UWB system are introduced. The peak amplitude, peak power and energy pattern of the uniform circular array are also given. At the same time, a fast beamforming algorithm is also proposed Computer simulation results show that the beamforming algorithm can adjust the azimuth of the main beam of the array aligned to the wave in real time to obtain the best signal reception
