Product Details
Product Overview
The SDL-T20 low-altitude surveillance radar combines azimuth mechanical scanning with elevation digital beamforming (DBF) to provide continuous 360° coverage and accurate moving target tracking. It delivers stable all-weather performance and supports detection of UAVs, helicopters, and vehicles up to 20 km. With high sensitivity and improved tracking precision, it is suitable for perimeter security, airspace monitoring, and critical infrastructure protection.
