Abstract
A phase deviation method determines translation between a reference and suspect signal by analyzing a phase deviation surface created by computing a deviation metric for phase shift estimates and then analyzing a surface formed from the deviation metrics for an array of translation offsets. The phase deviation method analyzes the deviation surface to determine a translation offset that minimizes phase deviation. This method is applied at increasing levels of detail to refine the translation offset.
