The DD-R37 X-band long-range quad-cell radar 1, Product Overview The DD-R37 X-band long-range quad-cell radar adopts a fully solid-state, fully coherent, and pulse Doppler system. This enables it to conduct all-weather detection and early warning of "low, small, slow" targets. Leveraging machine learning and AI recognition technologies based on "micro-Doppler signatures" and "flight path features," the radar effectively detects and classifies various targets, includ
