摘要
A system for differentiating between a signal from a physical source and a nonlinear signal effect includes an array, a delay control element and a signal processing element. The array is configured to detect a signal at a particular location using an initial time delay. The delay control element is configured to modify the initial time delay by a selected value and to apply a phase delay in an amount equal to the selected value and at a frequency of the signal. The signal processing element is configured to determine whether the signal corresponds to one of a physical source or a nonlinear signal effect based on whether a shift in a perceived location of the signal occurs.
