Abstract

Conventional monostatic radar systems typically exhibit a trade-off between long-range target detection achieved through narrow beams and short-range wide-area surveillance employing broad beams. Realizing both functionalities within a single system, enabling simultaneous surveillance and long-range target localization, poses a significant challenge. This paper presents a novel signal model and an all-digital frequency domain radar architecture leveraging first-of-its-kind space-code beamforming technique to achieve ubiquitous radar coverage. We show that the range-angle map can be estimated for all targets at full range-resolution for all beams compared to existing subcarrier based beamforming radars.
