The Radon Transform, True Time Delay Beamforming, and Ultra-Wideband Antenna Arrays (Invited Paper)
True time delay beamforming equals the Radon transform of space-time array data, enabling Radon-based filtering, semblance AoA estimation, triangulation, and hyperbolic integration to isolate near-field sources in ultra-wideband arrays.
