When designing a differential beamformer, it is of great importance to consider the white noise amplification problem and the array frequency response. Combining some results from the two previous chapters and exploiting the array redundancy, we show in the following how to derive differential beamformers that are robust to white noise amplification and whose beampatterns are almost frequency invariant.
