The traditional 3-D localization methods based on angle of arrival (AOA) using 2-D arrays has been well studied over the past few decades. However, in some situations, the sensors are only allowed to equip linear arrays for the space limitation. In t

Traditional Angle of Arrival (AOA) based localization methods require both the azimuth and elevation angle measurements to locate the source in 3D space. For that reason, sensors have to equip different kinds of 2D arrays. However, in some practical
