Security forces around the world are facing increasing threats: radio-controlled drones fly or hover over crowded stadiums, prisons and densely populated places. Unmanned aerial vehicles can monitor, record and transmit unauthorized video. You can also transport explosives, illegal items and other products. In order to respond to these threats, even terrorist attacks, murder of VIPs, etc., a new type of UAV jammer has been developed. The DroneBlocker jammer developed for military use can intercept small and medium aircraft in various ways.
Military personnel who want to protect bases and airports can use the system developed by IACIT from Brazil. Hyunnanique Nobre, general manager of IACIT’s general manager of sales and marketing, told janes.com that the Brazilian army is currently using portable jammer for various confidential applications, including VIP protection and important events.
According to reports, the Brazilian armed forces deployed the system during the Rio 2016 Olympic Games. The system has been successfully demonstrated in different countries in ten different infrastructures (airports, key structures, etc.). How does it work? This technology will interfere with the global positioning system (GPS) of the drone, forcing the aircraft to land smoothly. It can also force the drone to return to its place of origin. In addition, it prevents the imaging stream from returning to the operator, thereby hindering the tasks assigned to the drone.
Innovative technology can be used with multiple sensors. The company has developed an image processing algorithm that can identify targets such as drones from the video of surveillance cameras installed along the perimeter. The camera subsystem detects the target and sends a message or trigger signal to the interference subsystem to activate it. Radio frequency (RF) sensors detect targets by receiving RF signals from a database and looking for signature protocols that match the signals generated by the aircraft and/or its operators. According to the company’s website, there are two versions, military 110 and civilian 0200.
The system consists of camera, HF receiver, acoustic sensor (optional), radar (optional) and jammer, all of which have been integrated. It provides 24-hour protection, completely independent operation (no operator required) and the creation of event records. The configuration is very flexible and product versions are provided, with output power of 1 W, 10 W, 50 W, and 100 W for each channel. The platform includes installing the antenna on the roof of the building to be protected or on the portable mast to perform special tactical missions or major events.
