Wideband beamforming with constant beamwidth is one of the key problems in array signal processing. In this paper, a method based on uniform sidelobe is given. And the frequency response needed to realize constant beamwidth for subband components of the signal is computed and filter with FIR filters. This method is suitable for uniform linear array, and is also effective when the element has its own pattern or when its location is inaccurate. Computer simulation shows the feasibility of this method.
