AB  - This paper describes a technique for designing a collection of beamformers, a "beamformer bank," that approximately produces a constant-amplitude panning law. Useful in multichannel recording scenarios, a point source will appear with energy above a specified sidelobe level in at most two adjacent beams, and the beam sum will approximate the source signal. A non-parametric design method is described in which a specified sidelobe level determines beam width as a function of arrival direction and frequency, leading directly to the number and placement of beams at every frequency. Simulation results using several microphone array configurations are reported to verify the performance of proposed technique.
