Detection and Surveillance of UAVs Based on RF and Radar Technology

Key Points

System detects unauthorized entry of UAVs using multiple sensor checks for higher accuracy.
Positive response from RF Analyzer, radar sensor, and optical camera confirms drone detection.
Drones are beneficial for services like contactless delivery, yet they threaten privacy and security.
Deploying an efficient anti-drone system is critical for sensitive areas to enhance security measures.

Abstract

Unmanned Ariel Vehicles (UAVs) popular among them are drones. Drones are used widely in many areas such as imaging, payload delivery, and recently amidst COVID-19 pandemic, for contactless delivery of medicines. Every technology has its pros and cons, while drones are being used for many useful purposes; they also pose a threat to personal privacy and national security. Therefore, it is of a great significance to deploy anti-drone system in a security sensitive area. So, we have developed a system using RF and Radar technology which aims in detecting the entry of an unauthorized UAV into the restricted area. The system has been designed in such a way that there are multiple checks to detect the presence of a drone. The drone detection unit makes use of a Radar sensor, RF Analyzer and an optical camera. Positive response is mandatory from all the three sensors in order to confirm that an unauthorized UAV has entered the restricted area.
