Yes, drones can be detected by radar. Radar detection systems use a cross-section detection reading that interprets signal pulses to identify drone activity. These radar devices range in ability and accuracy.
Hello everyone! My name is Lavelle and I am a long-time drone enthusiast and professional drone pilot. I have actually been on both sides of this discussion, detecting drones flying over my home at night and having my drones detected by others while conducting business with my drone.
In this article, I will address exactly what radar detection is and how radar detection works. I will also cover some of the types of radar detection and some types of drones that can be detected by radar.

Key Takeaways
- Radar detection devices are great tools for detecting drone activity.
- Regardless of size or model, the majority of drones can be detected.
- The radar cross section (RCS) is critical to detection and is a part of most radar detection systems.
Can Drones Be Detected By Radar?
Modern radars are using radar cross-sections (RCS) to measure detectable objects in their path.
When an object comes into the path of the radar, a signal is sent to the radar’s signal receiver. The receiver then analyzes the signal and provides detection data. This way a radar can detect the majority of drones.
What Kind of Radar Can Detect a Drone?
To detect drones, high-resolution radar is used. The signal reflected from a drone is sent back to the receiver and matched against a robust database of signals taken from other drones.
As the signal matches a signal in the database, it provides feedback indicating that a drone is in the radar’s path.
With the advancements of Artificial Intelligence (AI) and Machine Learning (ML), radars can now more accurately recognize drone signals and detect drone activity.
What Kind of Drones Can Be Detected?
Radar can detect all types of drones. If a drone uses a radio frequency (RF) or a GPS signal or even a cellular frequency, radar can pick it up.
Radar is limited in detecting the size of an object, but any drone crossing its frequency path can be detected.
How Far Can a Radar Detect a Drone?
The radar cross section (RCS) determines how far a radar can detect a drone. The larger the RCS, the farther away the radar can detect activity.
Generally speaking, radar can detect a drone approximately 1 mile away.
However, that distance depends on the size of the drone. A larger drone may be detected farther away while a very small, recreational drone may not be detected until it is much closer to the radar.
Final Thoughts
Radar detection is a good option for detecting drones. The radar cross-section is the main determining factor in detecting drones. Any drone can be detected by radar but the larger drones are the most likely to be detected at the farthest distance.
In addition to radar detection devices, there are applications that can be used as radar detection methods as well.
