Abstract: The calculation of wideband digital beamforming using traditonal methods is so large that it is hard to realize in project. This paper describes a wideband digital beamforming method on the base of stretch processing for linear frequency modulated (LFM) waveforms. This method offers advantages that are moderate data rate for wideband signal processing by reducing the signal bandwidth greatly. In addition, the method not only can get high range resolution of wideband array radar, but also can form good shape pattern with null at interference, as the simulation results show. To the most important, this method compared to traditional methods is easier for engineering implementation greatly.
