The integration of Radio Frequency (RF) technology is essential for enhancing the capabilities and operational efficiency of unmanned aerial systems (UAS), commonly known as drones.

Recent advancements in Unmanned Aerial Systems (UAS) have led to improvements in communication and navigation, as well as applications such as aerial surveillance, tactical operations, observation, and agricultural monitoring. However, despite these significant benefits, malicious drones present a serious threat to sensitive locations, including airports, public safety facilities, and nuclear power plants. This situation underscores the urgent need for effective surveillance solutions. To address these challenges, the discussion will begin by highlighting the importance of deploying an RF technology detection system. This system comprises wideband Software-Defined Radio (SDR) receivers, a high-power amplifier, and monitoring antennas, along with high-gain direction-finding (DF) antennas. Such a setup is crucial for preventing unauthorized communications from unwanted UAS. We will also explore various methods for neutralizing threats posed by drones, which may include spoofing their communication or GPS signals, employing physical interception through radio technology, and capturing UAS using other physical means. Additionally, we will examine how RF sensors can provide accurate detection and classification of these hostile systems. The talk will outline major types of UAS technology, their applications, and necessary considerations.

Furthermore, we will analyze different RF bands and their suitability for specific drone applications, such as long- range control, real-time video transmission, and autonomous flight operations. Finally, we will present techniques and approaches in RF technology, including the adoption of Smart Sweeping Jamming techniques. This advanced method aims to enhance reliability and security while countering malicious activities that compromise privacy and threaten both civilian and sensitive infrastructures.
