At the IDET trade fair in Brno, Retia presented ReCas, a new complex anti-drone system. At the CSG stand, Marek Holeček, commercial director of military and security systems at Retia, explained its functions.

The threats associated with the operation of unmanned vehicles, such as drones and munitions, are becoming more sophisticated every day. Therefore, Retia tried to respond to this dynamic development with a solution that will be as comprehensive as possible, and will thus cover a large number of potential threats associated with unmanned vehicles.

The result of the development is our own control software (so-called C2 or Command and Control), which represents a kind of "central brain" of the entire system, into which it is possible to integrate individual components (elements) as well as those of third parties based on specific customer requirements and declared use cases .

The complexity of the ReCas anti-drone system is based on its modular architecture, where the customer has the option of choosing individual components for two hardware parts of the system, both the sensor part and the effector part. The sensor part of the system is used to detect threats and the effector part to eliminate them.

In the case of the ReCas anti-drone system, the cornerstone of the sensor part is the 3D radar ReGuard produced by Retia, which is very compact and, thanks to its technical parameters, ideal for protection systems against unmanned vehicles. The unique parameters and unprecedented range of the ReGuard 3D radar then guarantee an early warning of an approaching threat, giving the operator more valuable time (not only) to decide how to react to the detected threat, but also very important time to eliminate it.

Another integral component within the sensory part is the RF - detector, which serves to identify the directions and frequencies used by potential threats (sensor for RF radio reconnaissance). The electro-optical sensor then serves to classify and confirm previously detected targets based on optical sensing in day and night mode.

The effector part of the ReCas solution uses standard electronic interference (so-called soft killing). In the case of the ReCas system, Retia uses the integration of the jammer directly on the optical system, thanks to which it is possible to monitor the UAV's reaction to the jamming in real time. If necessary, the system can also be extended with means for shooting down the target (hard killing), which are also sometimes called lethal effectors.

Dozens of visitors and media representatives did not miss the ceremonial presentation of the ReCas system at the CSG stand on Wednesday, May 24.
