DOA estimation

Direction of Arrival (DOA) estimation is a technique used to determine the specific direction from which a signal, such as sound or radio waves, originates. By using multiple sensors or antennas, the system measures the time or phase differences of the incoming signal at different locations. Analyzing these differences allows the system to calculate the angle or location of the source relative to the sensors. DOA estimation is widely used in radar, sonar, wireless communications, and audio systems to identify and locate signal sources accurately.
