At least 31 Russian airports are planned to be equipped with UAV detection and countermeasure systems. This became known at the end of 2023. One of the first to receive such equipment was Moscow's Sheremetyevo Airport, where a radar-optical complex "Enot-SD" with additional software from Kaspersky Lab was installed.
Purchases of similar equipment have also begun in other regions. In particular, according to the online publication "CNews", Yuzhno-Sakhalinsk Airport named after Anton Chekhov has allocated 294.6 million rubles this year for the purchase of anti-drone equipment.
Applications for the tender on the public procurement website closed on June 24. The technical specifications state that "Enot" radar stations and the "Polyana" unmanned aerial vehicle countermeasures system will be purchased for the Yuzhno-Sakhalinsk airport. Most likely, "Polyana-D4M1" is meant.
What is known about "Enot"
The "Enot" radar was developed at the Scientific and Production Center "Electronic Computer and Information Systems" (JSC SPC "ELVIS"). It automatically detects drones, including ultra-small objects weighing from 0.25 kg, as well as ground and surface targets. After that, it measures coordinates, performs auto-tracking, classification, and target designation for optoelectronic and other means.
The radar recognizes and determines:
- small drones (effective scattering area from 0.01 sq. m) — at 3,000 m;
- ground or surface targets (effective scattering area from 0.5 sq. m) — at 4,700 m;
- cars on land or boats on water (effective scattering area 5.0 sq. m) — "Enot" will see at 8,300 m.
"Enot" with a multi-beam receiving antenna has the ability to programmatically integrate third-party systems into it, and it can integrate into third-party systems. This is facilitated by open protocols of any level of detail, from source data to target cards.
What is known about the "Polyana-D4M1" system
The automated control system "Polyana-D4M1" is used to control an anti-aircraft missile brigade or a mixed grouping of air defense forces. Through command posts, it can work with SAM systems such as the S-300 and Buk, and a mixed grouping of SAM (SAM) systems such as the S-300, Buk, Tor, and Tunguska.
It is responsible for ensuring the safe flight of aircraft, collecting and processing radar information, alerting about the air situation, and managing on-duty forces. Also, "Polyana-D4M1" automatically registers and documents the received and transmitted information, helps to distribute efforts in the areas of interaction when repelling air attacks, and can coordinate combat operations.
