Countering the Drone’s Threat by Radar – Technical Challenges and Perspectives

#Drone #Radar #detection #classification

Nowadays the increasing use of remote-controlled mini drones has become a real threat to the air traffic management. They may be misused for criminal acts or even terrorist attacks, and pose serious threats for the public security. Thus, accurate detection and classification of mini drones are highly essential and critical. Comparing to other types of sensors, radars show superior performance for their wide, long-range and rapid surveillance capabilities in all weather conditions, which are therefore widely adopted as an effective sensor to detect the drones. It is well known that the micro-Doppler signatures generated by the drones’ rotating blades have been popularly used for the drone detection and classification in many literatures. However, the behaviors of micro-Doppler of drones vary significantly for different radar operating modes. It may not be easy to capture the micro-Doppler signatures of drone in the real scenarios. This talk addresses the practical issues for drone detection as well as the suitable radar-based solutions for countering the drone’s threat in urban environment.
