Semi-Coprime Array with Staggered Beam-Steering of Sub-Arrays [PDF]
Sensors, 2023 A split-aperture array (SAA) is an array of sensors or antenna elements in which the array is split into two or more sub-arrays (SAs). Recently proposed SAAs, namely coprime and semi-coprime arrays, offer to attain a small half-power beamwidth (HPBW ...
