Drone radar detection technology leverages the principle of electromagnetic wave reflection, emitting radar waves and receiving echoes to locate and track drones. This technology is capable of penetrating most non-metallic materials, effectively detecting even stealth drones constructed from composite materials. A typical drone radar detection system comprises a radar transmitter, receiver, and signal processing unit. Through sophisticated calculations, it can provide precise information about a drone's location, speed, and direction.

Key Technologies and Operational Principles

• Active and Passive Detection: Active detection involves the transmission of radar waves and reception of reflected waves to pinpoint targets, whereas passive detection relies on intercepting a drone's own radio signals or radar reflections. These two techniques complement each other, enhancing the system's overall detection capability and resistance to interference.

• Multiple Input Multiple Output (MIMO) Technology: MIMO technology utilizes multiple antennas for both transmission and reception, significantly improving radar resolution and detection accuracy, particularly suitable for detecting small drones in complex environments.

• High-Frequency Carriers: Employing high-frequency carriers in X-band and W-band provides shorter wavelengths, enhancing radar resolution, which is crucial for detecting small, slow-moving drones.

Applications and Challenges

Drone radar detection technology finds extensive application in airport security, border surveillance, and the protection of critical infrastructure. However, ongoing optimization and upgrades still face challenges, including distinguishing drones from natural objects like birds, reducing false alarm rates, and maintaining stable detection capabilities under adverse weather conditions.

As a cornerstone of airspace security, the continuous development and enhancement of drone radar detection technology are essential in addressing the challenges posed by drones. By integrating active detection, passive detection, and MIMO technology, drone radar detection systems offer more accurate and comprehensive situational awareness in the air, providing robust support for the protection of critical infrastructure and public safety.
