Security forces around the world are facing a growing threat: radio-controlled drones that fly or hover over crowded stadiums, prisons and places with a high concentration of people. The drones can spy, record, and transmit unauthorized videos. You can also transport explosives, illegal goods and other products. and even carry out terrorist attacks, murder VIPs, etc.
In response to these threats, a new drone jammer for unmanned aerial vehicles (UAV) has been developed. The DroneBlocker jammer developed for military use can block small to medium-sized aircraft in various ways.
The system developed by IACIT from Brazil can be used by military personnel who want to secure bases and airports. The Brazilian army is currently using the jammer for various confidential applications, including VIP protection and important events, as Henrique Nobre, IACIT General Manager for Sales and Marketing, told janes.com.
The Brazilian armed forces reportedly deployed the system during the 2016 Rio de Janiero Olympics. The system has been successfully demonstrated in different countries in ten different infrastructures (airports, critical structures, etc.).
How does it work? The technology can interfere with a UAV’s Global Positioning System (GPS), forcing the aircraft to land smoothly. It can also force the UAV to return to its place of origin. In addition, it can prevent imaging streams from returning to the operator, thereby frustrating the mission assigned to the UAV.
The innovative technology works with several sensors. The company developed an image processing algorithm that allows targets such as UAVs to be identified from the videos from surveillance cameras installed along a perimeter. The camera subsystem detects the target and sends a message or trigger to the jammer subsystem to activate it.
A radio frequency (RF) sensor detects targets by receiving the RF signals with a database and looking for a signature protocol that matches the signal generated by the aircraft and / or its operator. According to the company’s website, there are two versions, the military 110 and the civil 0200.
The system consists of cameras, RF receivers, acoustic sensors (optional), radar (optional) and signal jammer, all of which are integrated. It offers 24-hour protection, completely independent operation (operators are not required) and the creation of event records. The configuration is flexible and offers product versions with an output power of 1 W, 10 W, 50 W and 100 W per channel.
The platform includes the installation of antennas on the roof of the structures to be protected or on portable masts for special tactical missions or for protection against major events.
