In modern warfare, drones have become one of the most dynamic and threatening components, both on the battlefield and in the rear of a warring country. FPV kamikaze drones, reconnaissance quadcopters, and heavy loitering munitions all create a critically high risk for personnel and equipment, rear-area facilities, and the civilian population. Therefore, technologies for the timely detection of drones are a key element of tactical safety for military units and civilians in frontline regions. A technological solution exists today that can save the lives of you, your comrades, your family, and loved ones.

This solution is the DR400-E portable handheld drone detector from the Chinese company TATUSKY, whose official partner is Defense Group

Technical Specifications of the DR400-E

The device consists of:

• A detection host – a portable radio frequency scanner.

• An information reception terminal – a smartwatch that duplicates real-time alerts.

The DR400-E operates based on:

• Low-power digital reception.
• Ultra-wide spectrum frequency analysis.
• Algorithms for identifying UAV types.

• A highly efficient external antenna.

Thanks to this device:

• Various types of quadcopters, drones, fixed-wing UAVs, and FPV drones are recognized.
• Audio, visual, and vibration alarm signals are provided.
• Data is transmitted to the watch for notification.

• It enables coordinated work within a team.

Its main advantage is the speed, direction finding, and identification of the drone or loitering munition type. This is critically important both in combat conditions and during air raid warnings.

When Every Second Counts

Under standard conditions, a UAV operator launches a drone from a distance of 1-2 km from the target. The DR400-E is capable of “catching” the characteristic signal of a remote controller or data link before the operator visually spots the drone. This means the detector genuinely saves the soldier precious time, which drastically increases survival chances.

Operations of Mobile Teams and Air Defense Units

Mobile teams hunting enemy FPV drones can use the DR400-E for:

• Determining launch direction.
• Understanding operator activity in the combat zone.

• Detecting “hot spots” where enemy drone swarms are operating.

This allows for locating camouflaged drone launch sites in wooded areas, abandoned farms, or private sector buildings. Thanks to early signal detection, a mobile team is capable of intercepting an enemy operator.

Protecting Headquarters, Communication Hubs, Rear Units, and Equipment

The DR400-E works effectively as an element of a local security system. The device constantly scans the airwaves, and any UAV activity within its detection radius is immediately registered.

This allows users to:

• Avoid “silent” approaches by reconnaissance drones.
• Prevent artillery correction.
• Protect equipment from FPV strikes.

In rear areas, there have been frequent cases where the DR400-E picked up signals from commercial drones in the airwaves, which were being used by the enemy as spotters or reconnaissance assets. This is particularly relevant:

• Near ammunition depots.
• At convoy assembly points.
• Around artillery positions.

• At critical infrastructure sites.

The DR400-E is not just a gadget; it is an element of tactical advantage that genuinely reduces losses on the battlefield and in civilian life within a war-torn country.

Key Advantages of the Device:

• Portability and autonomy.
• Ultra-wide detection spectrum.
• Accurate identification of drone types and some missile types.
• Instant notification via the smartwatch.
• Enhanced effectiveness for mobile teams, on the front line, and in the rear.

• Capability for unit coordination.

In modern warfare, where the drone has become a kind of “Wunderwaffe of the 21st century,” having such systems is a matter not of comfort, but of survival.
