The increasingly widespread use of sensor and actuator networks and in general\nof the Internet of Things (IoT) in several areas of precision, imposes\nupon localization systems that can often equip them with a robust and more\nprecise localization. It is in this sense that UWB technology has proved to be\none of the most powerful communication technologies for these localization\nsystems; thanks, in particular to the bandwidth occupied instantaneously by\nthe signal allowing a very fine temporal resolution. Constructors have set up\nlocalization kits based on various technologies. These kits facilitate in a way\nthe work of localization of users. In this paper, we present results on the performance\nstudy of the Decawave PDoA Kit. This Kit uses the PDoA (Phase\nDifference of Arrival) to determine the Angle of Arrival (AoA) parameter\nwith UWB technology. This study is in context of localization by AoA for an\napplication to protect agricultural crops against grain-eating birds. The results\nof the study show overall AoA measurement errors around 10 degrees in\nan ideal environment.
