ReGuard is a multi-purpose 3D radar for detecting and simultaneously tracking ground targets and slow, low-flying targets with a small radar cross section (LSS, UAV). ReGuard scans the space using electronic beam deflection. The radar can be supplied with a fixed or rotating base.

ReGuard is designed for two basic uses: either as a stand-alone sensor or as an integral part of a complex system. It can be adapted to the customer’s wishes and the nature of the object under guard, so it is highly suitable for solving various tasks.

Basic characteristics

Technology

  • 3D AESA technology with electronic beam steering in elevation and azimuth
  • Rapid space searching using multiple received beams
  • Only solid state technology to ensure high system reliability, including part redundancy
  • Monopulse processing in azimuth and elevation to accurately assess coordinates
  • Advanced signal and data processing to suppress clutter (including birds and cars)
  • Data network interface (ASTERIX output, remote control, etc.)
  • Built-in test equipment for automated system diagnostics
  • Can be operated in 24/7 mode

Configuration

Portable configuration

The radar head is mounted on a tripod, making it easy and fast to change its position. These advantages can be primarily used for temporarily securing important geographical points or border control.

Static configuration

The radar head is firmly located in a stationary place, such as a building or mast. This configuration is suitable for the long-term security of important objects, such as power plants, airports, chemical plants, industrial plants, etc.

Mobile configuration

The radar head is integrated on the vehicle or on another customer-defined platform. This integration makes it very easy to guard large gatherings, concerts, sports matches or VIP zones.

Technical description

Border protection

When protecting borders, ReGuard ensures that no person, vehicle or drone crosses the border without the radar operator knowing. Not only does ReGuard give an early warning and valuable reaction time to an effective response, but it also protects a wide strip of territory. When ReGuard is suitably located, its range covers up to 22 km of border in the horizontal plane and can also detect possible threats up to 8 km behind it.

In an anti-drone system

ReGuard can also be used as the radar sensor in an anti-drone system, where it detects LSS up to a distance of 18 km. Its highly accurate data on a target’s position can also be used to guide the reaction to the drone. Every anti-drone solution must have a radar sensor like ReGuard if it wants to provide full protection.

Use in an air defence system

The highly accurate radar data generated by ReGuard , thanks to its high technological sophistication, helps to create a very efficient air defence system when combined with a powerful weapons system, the integration of this data and an efficient system for transferring it.

Protecting important buildings

The increasing cases of UAV intruding into the grounds of nuclear power plants, industrial or development facilities shows just how inadequate the protection against this type of threat is. Effective detection makes it possible to respond in time and prevent material and human loss. ReGuard can pinpoint a small commercial drone at a distance of 6 km, which is its full range when flying at maximum speed. This means the user gains a valuable 15 minutes to respond to the threat.

Protecting airports

Airports are one of the most vulnerable facilities as far as small UAV are concerned. Even if unintentional, simply being present in the airport’s reserved area disrupts its operation and leads to significant economic losses. Unfortunately, there are also examples of the deliberate misuse of drones for terrorist acts, e.g. the threat of deliberately flying a drone into an aircraft engine at takeoff is horrifying. With ReGuard , airport security units acquire a tool that allows them to prevent both minor and completely irreparable damage. In addition, thanks to full records on the flight paths of all drones within range, it makes it very easy to find a drone user who might have posed a risk to running the airport. Last but not least, ReGuard is highly efficient in terms of its range. By using just one sensor it is able to cover almost the entire controlled traffic region (CTR) of the airport.
