Claim 8:
9. A linear array (LA) comprising:
a desired number of microphones linearly disposed and spaced with desired inter-microphone distances, the desired number of microphones and the desired inter-microphone distances verified by:
generating a steering vector for the LA having preselected parameters;
generating a constraint matrix based on the steering vector;
reformulating the constraint matrix based on a microphone response matrix and a steering matrix;
obtaining a beamformer by applying a minimum norm solution in terms of the constraint matrix;
verifying a desired characteristic of the LA by calculating the beamformer for a desired direction; and
constructing the LA based on the preselected parameters and the beamformer.
