ADRJ

Anti-Drone Radar Jammer

Unlike the Anti-drone systems on the market, which have the characteristic of being made up of separate sub-systems to carry out the functions of:

Radar
DF/RF Scanner
Jammer
Optical Identification

VirtuaLabs proposes a solution based on an intimate integration of the functions which has allowed the optimization of the performances offered and the implementation architecture.

In fact, the ADRJ system is made up of four panels, each one of them contains:

one of the four fixed faces of an S-Band Radar, with monopulse capability to improve detection accuracy. This section is also capable of performing a jamming function in the 3.0-5.85 GHz band
one of the four sections that allow you to perform the RF Scanning function in the 0.4-6 GHz band and the jamming function in the 0.4-3 GHz band.

Taken all together, the four panels allow total and instant coverage of the above-mentioned functions over a 360° angle without any moving parts.

In fact, the RF signals detected by the four panels are locally sampled at high frequency and digitized before being sent via optical fibre to the MDPC (Main Digital Processing Cabinet).

Similarly, the jamming commands are processed in the MDCP and sent, again via optical fibre, to the four panels for the local generation of the deception/jamming signals.

It is important to underline that the use of the Radar, also for Jamming activities, allows the generation of high powers to disturb at great distances:

the Commands Receiver of the drone
the Commands stations Receiver (DCS-Drone Command Station) if in visibility
the GNSS (Global Navigation Satellite Systems) Receiver

A Visible/IR optical camera is then added to the system capable of tracking drones on Radar designation and confirming their presence.
ADRJ can be installed in a fixed location or on a mobile vehicle

ADRJ Mode of Operation

Possible Scenario

A possible (naval or ground) scenario where a kamikaze drone is present is reported in figure. In the figure it is possible to note the GNSS signals that provide the drone its position, the TV or SAR kamikaze drone homing sensor, the TLC Link between the drone and its Drone Control Station (DCS). DCS can be installed on ground or in a movable platform like aircraft /helicopter or ships.

Option: Add-on Ku Kit, to deal with long range UAV controlled by satellite link.
