Three-phase sample timing on a wideband triangular array of 4/3 the usual density reduces the Nyquist rate for far-field signals by two thirds
RF-sampled microwave arrays are often limited by the analog-digital conversion speed available. Here the nominally required speed is reduced by a factor of three without aliasing of far-field plane-wave information by using three sample-timing phases on a triangular planar array with 4/3 the element...

| description | RF-sampled microwave arrays are often limited by the analog-digital conversion speed available. Here the nominally required speed is reduced by a factor of three without aliasing of far-field plane-wave information by using three sample-timing phases on a triangular planar array with 4/3 the element density of the usual "optimal" element layout. |
