NettetWe define the instantaneous phase difference intensity (IPDI) as an index that measures the similarity of instantaneous phase between the signals at the two receivers. Higher IPDI values signify that the two signals have a similar instantaneous phase at that time, which implies the arrival of a reflection from a cavity.
