Direction of Arrival (DoA)

Direction of Arrival (DoA) refers to the method of determining the exact direction from which a transmitted signal, such as a radio wave or sound, is coming. Using an array of sensors or antennas, systems analyze differences in signal timing or strength across these sensors to calculate the signal’s source direction. This technique is essential in applications like radar, wireless communications, and acoustics, enabling accurate localization of objects or sources in space without physically moving the sensors themselves.
