Seagull (airport airspace protection complex)

2023: Announcement of the complex

At St. Petersburg State Electrotechnical University (SPbGETU), LETI has developed a multimodal complex that allows you to detect and classify various objects in the air (drones, birds, etc.) in the vast space around the airport. The product was called "The Seagull," the Ministry of Education and Science said on July 11, 2023.

The system consists of three modules:

• passive coherent locator for detecting moving air targets within a radius of 30 km;
• a high-resolution video camera for determining the type of air object;
• an infrared camera capable of monitoring a flying object in the evening and at night, as well as in difficult weather conditions, such as fog. For reception and processing of video data, detection, classification and tracking of targets in the air is developed. software

In Russia, created a complex for protecting the airspace of the airport within a radius of 30 km connected to the telecom infrastructure

It is noted that the coherent locator is only its own transmitter. As a signal for location, the signal of existing transmitters from nearby telecommunication systems, for example, digital television, is used. Since the passive coherent locator itself is not a source of signals, it can be used unnoticed by intruders, the Ministry of Education and Science noted.

As the dean of the Faculty of Radio Engineering and Telecommunications of St. Petersburg State Technical University "LETI" Natalia Obukhova said, the version of "Chaika" created by July 11, 2023 has functionality that allows detecting flying objects within a radius of 1.5 km from the airport at any time of the day and in any weather and track their movement.

And if the targets approach a distance of 800 meters, the complex is able to recognize various types of air targets... Unlike the world's existing analogues, the Chaika complex can not only recognize what flies, for example, a drone or a bird, but also determine the species of these birds, "Obukhova emphasized.[1]
