[A beamformer is a spatial filter used to achieve spatial selectivity. However, it can be combined with a temporal filter to achieve both spatial and temporal selectivity. Such combined filter is essentially a multidimensional filter which is normally known as broadband beamformer. Broadband beamformers are useful in applications involving acoustic signal, for examples, speech acquisition for personal computers, teleconferencing and built-in hands-free communication in vehicles. Various design methods can be applied to design broadband beamformers. One such method is an optimisation-based approach where different optimisation criteria can be used to design beamformer weights for target applications. Typical beamformer designs are based on either nearfield or farfield source model, resulting in nearfield-only or farfield-only beamformers. However, it is possible to generalise the design formulation to cover both nearfield and farfield cases, thus achieving mixed nearfield–farfield beamformers, i.e. beamformers that work for both nearfield and farfield sources simultaneously.]
