![]() This countermeasure involves sending a new signal to the drone, replacing the communication with GPS satellites it uses for navigation. The United States Army uses the Marine Corps-sponsored LMADIS, or Light-Mobile Air Defense Integrated System - a mobile mounted anti-drone system which destroyed an Iranian drone in July 2019. Radio JammerĪ radio jammer is a static, mobile, or handheld device that uses a combination of radar and cameras to detect and jam drones in the sky by transmitting radio frequencies. Therefore, several security agencies use a mix of these technologies, which we’ve listed below. Counter-drone measuresĪlmost all major countries have introduced counter-drone measures to deal with rogue flying objects but the technologies to disable their navigation, interfere with their radio frequency, or even training eagles for countering small drones haven’t really proved foolproof. ![]() Security experts have also looked at optical cameras with infrared or thermal imaging capabilities to capture images of the drone and its payload. Radio Frequency (RF) Analysers is another such technique that can detect radio communication between a drone and its controller, but it’s useless against autonomous drones. However, a micro-doppler radar can detect speed differences within moving objects, allowing easy identification. ![]() But conventional systems are not meant for detecting small flying objects and even if they’re calibrated in such a manner, they can easily mistake a bird for smaller drones. The first process in countering a possible drone attack is to implement a monitoring equipment which would not only detect and distinguish drones from other objects such as birds and airplanes but also identify a particular model of drone and alert security officials to deploy countermeasures.Ī radar system can measure the direction and the position of flying objects by sending out radio signals and listening for the echo. And it further gained momentum in 2019 when Yemen’s Houthi rebels claimed responsibility for bombing two key Saudi oil installations. The discussions about such terror attacks began in 2018 when Syrian rebels used homemade drones to attack Russian military bases in Syria and Venezuelan President Nicolas Maduro narrowly escaped an assassination attempt by a GPS-guided drone attack the same year. Reports estimate 100-150 annual drone sightings, mostly for surveillance, near India’s western border. For one, terrorists from across the border have been dropping weapons and ammunition the country since the last three years in fact, in June last year, the Border Security Forces (BSF) neutralised a hexacopter in Jammu which was carrying a US-made M4 semi-automatic carbine, two magazines, 60 rounds of cartridge and seven Chinese grenades as payload. But for many, this attack wasn’t very surprising.
