A completely new unmanned aerial vehicle (UAV) detection technology is being introduced in the US, with the ability to listen to sounds and recreate 3D space images.
The device named UDL-64, developed by Hall Lidar (a unit specializing in developing target detection sensor systems, especially in the field of Lidar and security), is expected to open up a different approach in monitoring and dealing with UAVs.
Unlike traditional radar or sensor systems, UDL-64 operates completely passively, does not emit radio signals or depends on GPS.
Thanks to that, the device is almost invisible to the enemy's detection systems, while limiting the risk of jamming.
In terms of design, the device is compact in size, about 61cm in diameter, can be installed on tripods or fixed poles and deployed in just a few minutes.
The system integrates Wi-Fi, Bluetooth and 5G connections to easily connect to existing monitoring and control networks.
The highlight of UDL-64 lies in its ability to convert sound into spatial data.
The device uses a high-density microphone array combined with artificial intelligence to collect sound from the surrounding environment, then process it in real time to determine the direction and location of the source.
Thanks to pre-trained sound models, the system can recognize UAVs based on the sound of the propellers, while eliminating noises such as wind noise or urban noise.
In independent mode, UDL-64 can detect UAVs within a range of about 200m. When multiple devices are connected into a network, this range can be extended to 500m.
In network configuration, the system also uses methods to accurately locate targets, creating a widespread 3D tracking picture.
In addition, the device can integrate optical modules to increase accuracy while maintaining a compact design.
According to the developer, UDL-64 is designed to operate effectively in environments where traditional detection methods are limited, especially urban areas or complex terrain.
Production entirely in the US is also said to help ensure the transparency of the supply chain and meet security requirements.
Mr. David Hall, CEO of Hall Lidar, said the goal is to create a system that is both cost-effective and flexible in many usage scenarios.
In the context of UAVs becoming increasingly popular, detection solutions such as UDL-64 are assessed to play an important role in improving the ability to monitor and protect low-altitude airspace.
