Phase Difference of Arrival (PDoA)

Phase Difference of Arrival (PDoA) is a technique used to determine the direction from which a signal, like sound or radio waves, has arrived at a sensor or an array of sensors. It works by measuring the differences in the phase of the signal when it reaches multiple points. These phase differences allow us to calculate the angle of the incoming signal. This method is particularly useful in applications like locating sound sources, enhancing communication systems, and improving navigation technologies, as it provides precise directional information without needing additional complex equipment.
