Abstract:
1. A method for accommodating device and/or signal mismatch in a sensor array system having a plurality of sensors configured to generate a plurality of input signals including first and second sensors generating first and second input signals, the plurality of input signals being representable, at least one frequency, by input vectors each having a phase component and a magnitude component, including first and second input vectors, the method comprising: generating the first and second input signals from the first and second sensors; processing, using a processor, the first and second input signals, the processing including, at the at least one frequency, using the magnitudes of the first and second input vectors to obtain corresponding first and second magnitude-matched vectors each having a magnitude that is substantially equal to one of an arithmetic mean, a geometric mean, a harmonic mean, or a root-mean-square of the magnitudes of two or more input vectors; and generating an output signal having a magnitude that is a function of at least one of the first and second magnitude-matched vectors.
