ANKARA (AA) – FİRDEVS BULUT KARTAL – With the work carried out within the Turkish defense industry, the Acoustic Drone Detection and Tracking System was developed to detect drones by sound. SAĞLAMTEK Aerospace Defense, which works on reliable RF systems, antennas and electronic technologies specially designed for mission-critical applications, has turned its work on the detection of drones, which has become a significant threat recently, into a product.
SAĞLAMTEK aims to complement the radar and electrooptical sensors used for this purpose with the Acoustic Drone Detection and Tracking System. Ömer Boyraz, SAĞLAMTEK Aerospace Defense Embedded Software Team Leader, said that standard radars tend to detect living species or any moving object, and this reduces efficiency in complex areas. Pointing out that the solution they developed is complementary to radars, Boyraz emphasized that its biggest difference from standard RF radars is its passive operating principle.
Stating that active radars reveal their location and consume high energy when sending signals, Boyraz said, “Acoustic radar is a passive radar, it is only a listener. In this way, it operates with very low energy and can clearly detect the presence, absence and 360-degree horizontal-vertical orientation of the drone by focusing on the engine and propeller sounds.” he said. – Precise detection from a distance of 3 kilometers Referring to the early warning function of the system in case of threat, Boyraz stated that if the system is placed parallel to the area that is wanted to be protected or where the threat is thought to come, detection can be made from kilometers away.
Boyraz stated that the system can be applied wherever it is desired to monitor whether drones pass or not, and that it can also work as an acoustic radar system by integrating with camera systems and destruction vehicles. Stating that similar systems only report the presence of the drone and consume high energy, Boyraz said that the device can report the target direction and height with a small margin of error of 5 degrees.
Sharing data on the range of the system, Boyraz said, “We can continuously follow an average drone of 50 centimeters from a distance of 570 meters. “In large systems with 3-meter fixed wings, we reach a detection distance of up to 3 kilometers.” he said. Touching on the recent increase in swarm drone attacks, Ömer Boyraz pointed out that the system can detect swarms effectively from much longer distances due to the increase in sound and harmonics.
Boyraz emphasized that the system’s very short detection time of 250 milliseconds allows the simultaneous tracking of multiple threats coming from different directions. Boyraz, the bodyguard that can work with a power bank for infantry, stated that thanks to the modular structure of the system, it can be used by infantry in both fixed facilities (police stations, fortresses) and mobile units serving in the field. Pointing out that the system weighs less than 1 kilogram and can work even with a standard power bank thanks to its low energy consumption of approximately 30 watts, Boyraz explained that this feature ensures early warning of teams deployed or staying in the field against drone attacks.
SAĞLAMTEK company officials also noted that the system has been successfully tested and proven itself in the field with its current capabilities.
