Security forces around the world are facing a growing threat: radio controlled drones flying or hovering over crowded stadiums, prisons and places with high concentrations of people. The drones can spy on, record and broadcast unauthorized videos. They 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 unmanned aerial vehicle drone jammer was developed. Developed for military use, the DroneBlocker jammer can block small to medium-sized aircraft in a variety of ways.
The system developed by IACIT from Brazil can be used by the military who want to secure bases and airports. The Brazilian Army is currently using the jammer for a variety of confidential applications including protecting VIPs and important events, Henrique Nobre, IACIT general manager for sales and marketing, told janes.com.
The Brazilian Armed Forces reportedly used 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 disrupt a UAV’s Global Positioning System (GPS), forcing the aircraft to land gently. It can also force the UAV to return to its original location. Additionally, it can prevent imaging streams from returning to the operator, thereby thwarting the mission assigned to the UAV.
The innovative technology works with several sensors. The company developed an image processing algorithm that could detect targets such as UAVs based on the video 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 jammers, 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.
