| dc.description.abstract | In recent years, UAV (Unmanned Aerial Vehicle) technology has been increasingly applied across various fields, extending beyond its initial military applications. With advancements in technology and the evolution of temporal and spatial contexts, UAVs are now utilized for monitoring and surveying diverse environments. They can be equipped with various sensors to collect ground data for monitoring and analysis surface conditions. Additionally, UAVs can also be equipped with different devices for use in industries such as agriculture, such as pesticide spraying and irrigation in agriculture, automated logistics and transportation, urban planning, disaster relief missions, multimedia and entertainment (e.g., film production and stunt performances, among others. These applications help reduce labor costs and enhance overall work efficiency.
However, with the increase in UAV applications, there arises a significant issue of UAVs violating regulations by entering restricted airspace, posing threats to personal safety, privacy, and public order. Therefore, preventing illegal UAV intrusions has become an essential concern.
This thesis studies the development of a low-cost, high-accuracy real-time UAV tracking system. The system utilizes the SDR (Software-Defined Radio) platform developed by the Industrial Technology Research Institute (ITRI), combined with a Uniform Linear Array (ULA) antenna as the receiving end. By employing RF (Radio Frequency) detection of UAVs and integrating beamforming technology with Direction of arrival (DOA) estimation algorithms, the system estimates the incident angle of UAV signals and tracks the target UAV in real-time. | en_US |
