Abstract :
A method for producing a constant-phase calibration signal anywhere along a transmission line is discussed. Based on the multiplication of two half-frequency signals flowing in opposite directions along the line, a method has been developed particularly for phasing a large radiotelescope array. This method has been used for the adjustment of the University of Sydney one-mile cross-type radiotelescope; the performance of the system is discussed.
