An alarm from ENOT means that an automated airspace or security radar system has detected a potential threat, such as an unauthorized drone (UAV), vehicle, or intruder within a protected perimeter. The ENOT Radar Station (РЛС ЕНОТ) is an advanced multi-target tracking system widely integrated with perimeter defenses like Kaspersky Antidrone and automated security arrays like TELENOT hazard alarms to guard critical infrastructure. If you are an operator, security administrator, or facility manager who just received an ENOT alert, immediate validation and triage are required. Why Did the ENOT Alarm Trigger?
Understanding the root cause of the alert will help you determine the correct protocol. The ENOT radar array utilizes ultra-sensitive Doppler radar tracking that classifies targets based on radial velocity, cross-section size, and trajectory. 1. Unauthorized Drone Activity (UAV)
The primary function of ENOT is the automatic detection of small and ultra-small unmanned aerial vehicles, starting from takeoff weights as low as 0.25 kg. It tracks common commercial targets up to 3,000 meters away, including consumer drones like the DJI Mavic and Phantom series. 2. Ground Perimeter Breach
Beyond airspace, ENOT provides comprehensive ground and water coverage. It triggers automated alerts when its 360-degree tracking system spots an unidentified person moving up to 4,700 meters away or an unauthorized vehicle up to 8,300 meters away. 3. Environmental Interferences (False Positives)
Because the system is configured to flag minor movements, it can occasionally suffer from environmental false alarms. Large birds, heavy storms, blowing debris, or trees swaying in extreme wind can briefly trick the Doppler velocity sensors into registering a moving hazard. Step-by-Step Solutions to Handle an ENOT Alarm
When an ENOT alarm sounds, follow this sequential response sequence to ensure public safety, protect your facility, and manage the system effectively.
Step 1: Read the Notification and Isolate Target Coordinates
Locate the Alert: Open your primary command station console or OT sensor dashboard.
Identify Coordinates: Extract the precise target azimuth, distance, and current radial speed from the real-time radar map.
Note the Object Class: Read the system’s internal automated classifier reading (e.g., “Drone,” “Vehicle,” “Person,” or “Unclassified”). Step 2: Cross-Verify Using the Integrated PTZ Cameras
Deploy Optical Tracking: The ENOT platform automatically interfaces with PTZ (Pan-Tilt-Zoom) cameras. Look at your secondary video monitor to see if the cameras have successfully swung to focus on the radar coordinates.
Visual Confirmation: Visually inspect the live feed to see if you can see a physical drone, a human intruder, or if the system was tripped by a flock of birds.
Step 3: Deploy Electronic Countermeasures (If a UAV Threat is Verified)
Engage Jamming Modules: If the target is confirmed as a hostile or unauthorized drone, activate the system’s integrated electronic warfare components (like the ENOT-SD array).
Suppress Signal Channels: Allow the system to project its protective radio-electronic barrier, which disrupts the drone’s navigation (GPS/GLONASS) and control frequencies, forcing it to land or return to its operator. Step 4: Triage, Mute, or Learn the Alert in the System
