Abstract
- The use of two extremely stable radio-frequency oscillators, one stationary and the other mobile, is described for measuring relative phase difference between widely separated elements of large aerial arrays. Results of measurements made at 80MHz on the 96-aerial Culgoora radioheliograph, using an atomic frequency standard for the mobile unit, demonstrate that the method is suitable for phase-calibration purposes.
