Beampattern design is an important topic in array signal processing in general. This chapter is dedicated to this matter but in the particular context of differential beamforming. From the different definitions and approximations of the beampatterns, we show how to design any desired DMA beampatterns of any orders. We discuss the nonrobust and robust approaches, the constant (or frequency-invariant) pattern design, and the weighted least-squares method.
