In modern warfare, drones play a crucial role, conducting not only reconnaissance but also engaging in offensive operations. As demonstrated in recent conflicts, their roles in both surveillance and attacks have contributed to the growing significance of drones on the battlefield. LESA is a next-generation, software-defined radio that utilizes a phased array antenna combined with cutting-edge IC technology to deliver highly accurate threat detection and classification. Its advanced X-band phased array radar technology can track nano-drones at distances of up to 7.0 km. LESA radars are designed for versatility, allowing for easy configuration and seamless installation on a wide range of vehicles or as stand-alone systems.
