The T20 is a lightweight, portable short-range continuous-wave radar featuring DBF digital beamforming and simultaneous multi-beam technology. It detects target speeds from 1 to 180m/s, with a pitch angle range of-5 to 60 degrees. The radar delivers angular accuracy of 0.3 degrees and distance resolution of 5 meters, with data refresh rates of 1/2/3 seconds. Capable of tracking over 500 targets simultaneously, it operates within a scanning range of 3000 meters altitude and 20 kilometers radius. Powered by a portable swivel mechanism, the system consumes less than 450W while weighing under 30kg. Even when paired with the compact DJI Mini series drones, it maintains detection ranges exceeding 6.5 kilometers. With a maximum transmission power of 40W, it ensures exceptional operator safety and urban environmental adaptability. Its ultra-low transmission power significantly reduces interception risks, enhancing battlefield survivability. Among low-power anti-unmanned/loitering radar systems, the T20 stands unmatched in technical performance.
