The equipment has two antennas (S-band), horizontal and vertical, and uses unique radar signal processing technology, as well as high-quality radar algorithms and software processing capabilities. Through the Doppler pulse solid-state S-band radar, digital array active phased array 3D surveillance radar, can be all-weather, all-day continuous detection and tracking of the movement of the target in the surveillance area, in the effective distance can be detected than the sparrow small bird target (diameter of 3cm), and at the same time, real-time detection and early warning of migratory bird flocks.
