UAV, commonly known as UAV, is widely used in surveying and mapping, aerial photography, rescue operations, shipping, law enforcement, agriculture and other fields. Although there is great potential to improve public safety, the use of drones can also lead to very unpopular situations, such as invasion of privacy and security, or property damage. Another issue of great concern is the use of drones to carry out terrorist attacks, which means posing a threat to public security and national security.

Radar technology is one of the solutions to monitor the existence of drones and prevent possible threats. Due to the different size, shape and composite materials of UAV, the detection of UAV is challenging.

Researchers from Aalto University (Finland), UCLouvain University (Belgium) and New York University (USA) collected a wide range of radar measurements aimed at improving the detection and recognition capabilities of drones. The researchers measured the radar cross section (RCS) of various commercial and custom drone models to show how targets reflect radio signals. RCS features can help identify the size, shape and material of drones.

"We measured the RCS of drones at multiple 26-40 GHz millimeter wave frequencies to better understand how to detect drones and studied the differences in scattered radio signals between drone models and materials. We believe that our results will be the starting point for the future unification of the UAV database. Therefore, all the research results have been published in conjunction with our research paper. Vasilisemkin.

The publicly available measurement data can be used to develop radar systems and machine learning algorithms for more complex identification. This will increase the detection of UAV and reduce the probability of fault detection.

"there is an urgent need to find better ways to monitor the use of drones. Our goal is to continue this work and extend the measurement movement to other frequency bands, as well as more types of drones and different real-life environments," VasiliiSemkin said.

The researchers suggest that 5G base stations could be built for monitoring in the future.

"We are developing millimeter wave wireless communication technology, which can also be used as a radar detection environment," said Professor Ville Viikari of Aalto University. "with this technology, 5G base stations can detect drones and so on.
