Near Field Tapering with Slepian Window: Balancing the Range Angle Sidelobe Trade off
Ahmed Hussain, Ahmed Sultan, Asmaa Abdallah +2
Near-field beamforming enables target discrimination in both range (axial) and angle (lateral) dimensions. Elevated sidelobes along either dimension, however, increase susceptibili…
Uniform Circular Arrays in Near-Field: Omnidirectional Coverage with Limited Capacity
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +1
Recent studies suggest that uniform circular arrays (UCAs) can extend the angular coverage of the radiative near field region. This work investigates whether such enhanced angular…
Joint Motion, Angle, and Range Estimation in Near-Field under Array Calibration Imperfections
