AReS Technologies

AReS Technologies is a Ukrainian defence firm developing a passive acoustic targeting system, also called AReS, that aims to track drones and missiles in real time as an alternative to radar and optical sensors. The system is built around a phased-array microphone array and what the company describes as bimodal beamforming, scanning the surrounding space with large numbers of sound “beams” so it can pick out both loud and quiet sources and separate them individually. Because it is passive, it emits no signal of its own.

According to reporting and field tests cited by the company, AReS can designate FPV targets at roughly 200 to 300 metres and Shahed-type drones at up to around five kilometres, and has been trialled during real Shahed attacks, cruise-missile launches and FPV-drone tests. Developers stress that the system is intended not only to detect a threat but to provide precise targeting data for the munitions engaging it, including in fog, cloud or darkness. The firm has said it was seeking grant funding through Brave1 , Ukraine’s state defence-innovation cluster, to support manufacturing, and that it is working on a compact version for mounting on ground robots to defend logistics routes against FPV attacks. The company indicates that many components are sourced externally while its boards and software are developed in-house.
