  Broadband beamforming is a technique to obtain the signal with a wide range
of frequencies. It maintains the signal integrity and spatial selectivity over
frequencies. This is important in several applications such as microphone
array, sonar array or radar where the operation range of the signal is several
octaves. Using uniform array for broadband beamforming is the old topic but
there is no available design method for the arbitrary beam patterns, except the
optimization methods. In this paper, we present a new method based on geometry
translation and coordinate transformation to design broadband beamformer for
arbitrary beam patterns. The new method uses less computation time than the
optimization methods and it could help to find a better configuration of the
array such as fewer sensors, smaller size.
