Theoretical analysis demonstrates that wideband signal can not be transmitted by using narrowband phased array in scenarios with large aperture and scan angle.Two wideband transmitting beamforming methods for phased radar based on the known waveform in the presence of large scan angle are proposed.The diagrams are given
and simulation results show the effectiveness of two methods.The novel methods employ digital processing in the time domain and are optimal.Compared with the beamforming method utilizing FIR filter consisting of tapped delay lines in the time domain and the beamforming technique with DFT in the frequency domain
the presented methods demand the smaller number of equipment and are easy to be implemented in engineering.
