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
- J. O. Coleman
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.
