| Abstract: | For correlation of coded waveforms, the nonlinear interaction process in a SAW convolver should ideally give an amplitude and phase independent of position. A new experimental method of measuring this spatial uniformity used CW test waveforms and gave a resolution of 25 ns?a considerably higher resolution than previously attained. |
