Coordinating ground base stations with high-altitude balloon platforms and low-earth-orbit satellites for unified 3D radar coverage.
Solar-powered autonomous HAPS aircraft lingering at 20 km altitude provide wide-area radar coverage over 200 km radii. Ground towers and HAPS share synchronized radar timing, detecting low-flying drones and ground vehicles.
Target tracks transition seamlessly across LEO satellite beams, HAPS platforms, and urban street-level micro-cells through standardized 3GPP non-terrestrial network (NTN) interfaces.
